Изобретение относитс  к области получении непредельных кетонов и их ацетоксипронзводных , которые могут найти применение, как полупродукты в органическом синтезе, в производстве душистых веш.еств и витаминов.The invention relates to the field of the production of unsaturated ketones and their acetoxyphosphonic derivatives, which can be used as intermediates in organic synthesis in the production of fragrant veshchestv and vitamins.

Известен способ получени  р, у-непредельных кетонов дегидратацией р-оксикетонов с выходом не более 20%.A known method for producing p, y-unsaturated ketones by dehydrating p-hydroxy ketones with a yield of no more than 20%.

Но известный способ не позвол ет нолучат1 р, Y-непредельные кетоны с достаточно хорошим выходом и пригоден дл  синтеза лишь отдельных представителей этого класса соединений .But the known method does not allow nluch1 p, Y-unsaturated ketones with a sufficiently good yield and is suitable for the synthesis of only certain representatives of this class of compounds.

у-Ацетокси-а, р-непредельные кетоны не онисаны в литературе.y-Acetoxy-a, p-unsaturated ketones are not described in the literature.

С целью повышени  выхода и расширени  ассортимента получаемых продуктов, предлагают способ получени  непредельных кетонов и их ацетоксипроизводных, который основан на использовании доступного и дешевого сырь  и осуществл етс  в м гких услови х.In order to increase the yield and expand the range of products obtained, a method is proposed for the production of unsaturated ketones and their acetoxy derivatives, which is based on the use of available and cheap raw materials and is carried out under mild conditions.

Способ заключаетс  в том, что алканоны, имеюндие по крайней мере Олтин вторнчный или третичный а - углеродный атом, подвергают взаимодействию с триацетатом марганца и алкенами , например 1-алкеном, при 30-70°С в присутствии каталитических количеств солн меди в среде нол рного растворител , предпочтительно уксусной кислоты или смеси уксусной кислоты с нетролейным эфиром, с последующим выделением целевых продуктов известными приемами. В образующейс  смеси продуктов, суммарный выход которых составл ет 65-100% па прореагировавший олефии,The method consists in that alkanones, having at least Oltin a secondary or tertiary a carbon atom, are reacted with manganese triacetate and alkenes, for example, a 1-alkene, at 30-70 ° C in the presence of catalytic amounts of copper suns in a medium a solvent, preferably acetic acid or a mixture of acetic acid and non-trated ether, followed by isolation of the target products by known methods. In the resulting mixture of products, the total yield of which is 65-100% of pasted olefia,

основным компонентом  вл етс  р, у-непреде ,тьны кетон, прп дальнейшем окислении которого в услови х процесса получаетс  у-ацетокси-а , р-нспредельный кетон. При увеличении количества вз того в реакцию триацетатаThe main component is p, y-non-vinyl, a ketone, the further oxidation of which under the process conditions is y-acetoxy-a, p-distributed ketone. With an increase in the amount of triacetate taken into reaction

При мол рном соотношенпи исходны кетоп: триацетат марганца 5 получают преимущественно смесь р, у- и у. 8-непредельных кетопов, при мол рном соотношении исходный кетон: триацетат марганца - 30 получают преимущественно р, у-непределы1ЫЙ кетон, прн мол рном соотнон1епии исходный кетоп: триацетат марганца --. 2 образуетс  преимущественно у, 5-непредельный кетон н у-ацетоксн-о, р11 ен р едел ьн ы и ксто н.manganese is mixed with the yield of p, y-limiting ketone and, accordingly, the yield of y-acetoxy-n increases. p-unsaturated ketone. With a molar ratio of the initial ketop: manganese triacetate 5, a mixture of p, y- and y is predominantly obtained. 8-unsaturated ketopins, with a molar ratio of the starting ketone: manganese triacetate - 30, predominantly p, y-indefinite ketone, and a molar correlation of the starting ketope: manganese triacetate -. 2, predominantly y, 5-unsaturated ketone n y-acetox-o is formed, p11 is en p and ny and xy n.
