Abstract

Phenanthrenequinone monoxime is prepared by refluxing together phenanthrene quinone, hydroxylamine hydrochloride, chloroform, and alcohol. 9-Amino-10-phenanthrol is prepared by passing H2S into a boiling alcohol suspension of phenanthrenequinone monoxime, and adding concentrated hydrochloric acid. a -Methyl-9 : 10-phenanthreneoxazole is prepared by refluxing together 9-amino-10-phenanthrol and acetic anhydride.ALSO:Cyanine dyes are prepared by known methods from alkyl quaternary salts of a -methyl-9 : 10-phenanthreneoxazole, e.g. by condensation of 2 mols. with an ortho ester of a carboxylic acid (e.g. trimethyl orthopropionate, methyldiethyl ortho - n - caproate, methyldiethyl orthoisocaproate, trimethyl orthovalerate, trimethyl orthoformate, triethyl orthoformate, trimethyl-orthobenzoate, trimethyl ortho-p-toluate, trimethyl ortho-g -phenoxybutyrate, and trimethyl orthophenylacetate) or by condensation of one mol. of the a -methyl-9 : 10-phenanthreneoxazole quaternary salt, one mol. of the ortho-ester, and one mol. of a heterocyclic nitrogen base or its quaternary salt, or by condensation with a quaternary salt of a heterocyclic nitrogen compound having a reactive thioether or selenoether group in a - or g -position to a heterocyclic nitrogen atom. 3 : 31-Diethyl-4 : 5 : 6 : 7 : 41 : 51 : 61 : 71 - tetrabenzoxacarbocyanine ethosulphate is prepared by refluxing together a -methyl-9 : 10-phenanthreneoxazole diethyl sulphate, triethyl orthoformate, and pyridine. 3 : 31 - Diethyl-4 : 5 : 6 : 7 : 41 : 51 : 61 : 71-tetrabenzoxacarbocyanine chloride and 3 : 31 - diethyl - 9 - methyl -4 : 5 : 6 : 7 : 41 : 51 : 61 : 71 - tetrabenzoxacarbocyanine chloride are similarly prepared. 11 : 3 - Diethyl-4 : 5 : 6 : 7 - tetrabenzoxa - 21 - cyanine p-toluene-sulphonate is prepared by refluxing together a - methyl - 9 : 10 - phenanthreneoxazole etho - p - toluenesulphonate, 2 - methylmercaptoquinoline etho-p-toluenesulphonate, alcohol, and triethylamine.
