Egnede løsningsmidler omfatter eter, benzen, kloroform eller tetrahydrofuran. Reaksjoner av denne type er normalt eksoterme slik at tilførsel av varme ikke er nødvendig. I virkeligheten kan kjøling under tiden være nødvendig for å styre reaksjonshastigheten„ Reaksjonen vil normalt utføres ■ The reactions are preferably carried out under anhydrous conditions in the presence of a base, such as e.g. pyridine or triethylamine, and in a solvent for the reactants. Suitable solvents include ether, benzene, chloroform or tetrahydrofuran. Reactions of this type are normally exothermic so that the supply of heat is not necessary. In reality, cooling during this time may be necessary to control the reaction rate. The reaction will normally proceed

Etter tilsetning omrøres reaksjonsblåndingen i ca. 1 time og tilla-tes å komme til romtemperatur. Blandingen vaskes flere ganger med vann og tørkes over MgSO^. Blandingen avfarves ved omrøring i ca. 1 time med aktivt trekull og konsentreres så ved inndampning med et utbytte på 242,1 g væske. Væskens struktur stadfestes ved N.M.R.-spektra. After addition, the reaction mixture is stirred for approx. 1 hour and allowed to come to room temperature. The mixture is washed several times with water and dried over MgSO4. The mixture is de-coloured by stirring for approx. 1 hour with activated charcoal and then concentrated by evaporation with a yield of 242.1 g of liquid. The liquid's structure is confirmed by N.M.R. spectra.

Deretter tilset- tact with a cultured bacterium or fungus in an artificial medium. The preliminary search is carried out by partially filling a 28.35 g ampoule with malt broth and a 28.35 g ampoule with nutrient broth. Then add-

Tilstrekkelig 1-bromacetoksy-3-butyn fortynnes i aceton for å gi en 0,5% løsning som så fortynnes i 20 ml's varme, modifi-serte Jack Meyers agarmedia. Fortynningene er slik at det.tilveie-bringes konsentrasjoner på 1 , 5, 10 og 50^,ug/ml av f or søks forbin-delsen i 20 x 100 mm petriskåler. Etter at agaren har stivnet, inokuleres hver petriskål med organismene Scenedesmus obliquus og Chlorelle pyrenoidosa. Prøvene får så vokse ved romtemperatur under fluorescerende lamper idet det anvendes en 14 timers lysperio-de hver dag. Etter to uker er resultatene som angitt i tabellen nedenfor: Sufficient 1-bromoacetoxy-3-butyne is diluted in acetone to give a 0.5% solution which is then diluted in 20 ml of warm, modified Jack Meyer's agar media. The dilutions are such that concentrations of 1, 5, 10 and 50 µg/ml of the test compound are provided in 20 x 100 mm Petri dishes. After the agar has solidified, each Petri dish is inoculated with the organisms Scenedesmus obliquus and Chlorelle pyrenoidosa. The samples are then allowed to grow at room temperature under fluorescent lamps, using a 14-hour light period each day. After two weeks, the results are as indicated in the table below:
Som det vil ses av forsøksresultatene kan forbindelsene As will be seen from the experimental results, the compounds can
i henhold til oppfinnelsen brukes til å drepe bakterier, alger og sopper. Forbindelsene kan påføres direkte på den spesielle uøns- according to the invention is used to kill bacteria, algae and fungi. The compounds can be applied directly to the particular unwanted
kede biologiske organisme eller den kan påføres på et sted som skal beskyttes. I hvert tilfelle er det naturligvis nødvendig at den uønskede organisme mottar en effektiv dose eller mengde, dvs. en mengde tilstrekkelig til å drepe eller hemme vekst."Forbindelsene kan påføres på eller i tekstiler, lær, maling, seper, papir, tre, plast, olje og hvilke som helst andre substanser som er ømfintlige overfor vekst av uønskede biologiske organismer. ted biological organism or it can be applied to a place to be protected. In each case it is naturally necessary that the unwanted organism receives an effective dose or amount, i.e. an amount sufficient to kill or inhibit growth." The compounds can be applied to or in textiles, leather, paint, soap, paper, wood, plastic , oil and any other substances susceptible to the growth of undesirable biological organisms.
Forbindelsene anvendes normalt med en passende bærer ogThe compounds are normally used with a suitable carrier and
kan påføres som et fint pulver, ved dusjing eller fukting, eller i form av en aerosol. Forbindelsene kan således påføres i kombinasjon med løsningsmidler, fortynningsmidler, forskjellige overfla-teaktive midler (f.eks. rensemidler, seper eller andre emulgerings-eller fuktemidler, overflateaktivé leirer) , bæremedia,bindemidler, spredemidler, fuktemidler og lignende. De kan også kombineres med andre biologisk aktive forbindelser, som andre fungicider, baktericider og algecider, insekticider, vekststimulatorer, acaricider, herbicider, molluscicider, etc., såvel som gjødningsmidler, jord-forbedringsmidler, etc. Forbindelsene i henhold til oppfinnelsen can be applied as a fine powder, when showering or moistening, or in the form of an aerosol. The compounds can thus be applied in combination with solvents, diluents, various surface-active agents (e.g. cleaning agents, soaps or other emulsifying or wetting agents, surface-active clays), carrier media, binders, spreading agents, wetting agents and the like. They can also be combined with other biologically active compounds, such as other fungicides, bactericides and algaecides, insecticides, growth stimulators, acaricides, herbicides, molluscicides, etc., as well as fertilizers, soil improvers, etc. The compounds according to the invention
kan brukes i kombinasjon med en inert bærer og et overflateaktivt middel eller emulgeringsmiddel, og kan også påføres i kombinasjon med andre biologisk aktive materialer, i sammenheng med en bærer og et overflateaktivt eller emulgerings-middel. De faste og fly-tende preparater kan fremstilles på hvilken som helst kjent måte. Da den nødvendige mengde av det aktive middel vil variere i henhold til den biologiske organisme som skal behandles, kan ikke nøyakti-ge mengder gis. Bestemmelse av den optimale effektive konsentrasjon for en spesiell anvendelse kan lett utføres ved rutineforsøk som vil være kjent for fagmannen. Som nevnt vil den anvendte mengde i et gitt tilfelle være en effektiv mengde, dvs. en mengde tilstrekkelig til å gi den forønskede type av regulering. can be used in combination with an inert carrier and a surface-active agent or emulsifier, and can also be applied in combination with other biologically active materials, in conjunction with a carrier and a surface-active or emulsifier. The solid and liquid preparations can be prepared in any known manner. As the required amount of the active agent will vary according to the biological organism to be treated, exact amounts cannot be given. Determination of the optimum effective concentration for a particular application can be easily performed by routine experiments which will be known to those skilled in the art. As mentioned, the amount used in a given case will be an effective amount, i.e. an amount sufficient to provide the desired type of regulation.
