ethylene chlorohydrin unexpectedly led to preferential formation

Reactions of 2-aminobenzothiazoles with ethylene chlorohydrin. molecular and crystal structure of bis[(3- β -hydroxyethyl)benzo-thiazolyl-2-indene]ammonium chloride

Hydroxyethylation of 2-aminobenzothiazoles by ethylene chlorohydrin unexpectedly led to preferential formation of 3-β-chloroethylbenzothiazolin-2-one. In the case of unsubstituted 2-aminobenzothiazole, we also isolated the target 2-indno-3-β-hydroxyethylbenzothiazoline and bis((3-/3-hydroxyethyl)benzothiazolyl-2-indenelamnionium chloride. As a result of reaction of 2-aminobenzothiazole with 3-β-chloroethylbenzothiazolin-2-one, we obtained 2-(benzothiazolyl-2-imino)-3-( β -(2-oxobenzothiazolin-3-yl)ethyllbenzothiazoline. The structure ofthesynthesized compounds was established based on x-ray diffraction, PMR, IR, UV

Process for the preparation of ethylene chlorohydrine

Abstract not available for EP0010013 Abstract of corresponding document: US4283577 This invention relates to the method for making ethylene oxide, characterized by the fact that ethylene oxide in the gaseous state is made to react with anhydrous gaseous hydrochloric acid, with the reaction medium likewise being maintained in the gaseous state during the reaction.
