| titleOfInvention | Process for the manufacture of conversion products of ethylenes |
| abstract | Ethylenic compounds of the general formula <FORM:0439545/IV/1> or <FORM:0439545/IV/2> (wherein R stands for hydrogen or a group of the type R<1>, R<1> for an amphoteric auxochrome or group imparting a positive character, R<11> for a monovalent atom or group) or acid addition products thereof are treating with nitriting agents and the resulting nitroso or isonitroso compounds are split up hydrolytically to carbonyl compounds or reaction products thereof. An amphoteric auxochrome is an aryl group or vinylene group; a group imparting a positive character is methoxy, hydroxy, amino, dimethylamino, phenylamino or an alkyl group, either alone or in conjunction with an aryl group or a vinylene group. Specified nitriting agents are nitrous acid, nitrosyl chloride, nitrosylsulphuric acid, nitrosyl perchlorate, nitrosylperchlorate, amylnitrite and ethylnitrite. In examples: (1) N-methyl-9-methylacridinium - methylsulphate is treated with sodium nitrite; N-methylacridone separates out; (2) a -a -tetramethyldiaminodiphenyl-b -phenylethylene is treated in acetic acid with sodium nitrite; the product is hydrolyzed by sodium carbonate or 5 per cent hydrochloric acid to give tetramethyldiaminobenzophenone; (3) methylpyronine chloride is treated with amylnitrite in acetic anhydride to give a cyanpyronine which is converted to tetramethyldiaminoxanthone by means of dilute caustic soda. Reference is also made to the production of aldehydes, ketones, lactones, pyrones, cumarines, flavones, xanthones, and acridones by the process of the invention. |
