发明名称 Halohydrin thioethers and method of preparation
摘要 Compounds of the structure R(SCH2CHOHCH2X)n when n = 1 to 4 and R is a hydrocarbon, ether, ester, acetal, hydroxy aliphatic, hydroxy aromatic, imide or amide group or halogenated derivatives thereof are prepared by reacting 1-halo-3-mercapto-2-propanol with an aliphatically unsaturated compound using free radical initiators as catalysts. The compounds in which R is an unsaturated aliphatic hydrocarbon group of 2 to 24 carbon atoms, or an unsaturated cycloaliphatic group, and those in which the aliphatic or cycloaliphatic group is connected to two or more -S-CH2CHOHCHCl groups, and compounds where R is an alkylene substituted aromatic group and hydroxy, thioalkyl, alkoxy, aryloxy, ester, carbamidoalkyl and sulfamidoalkyl, halogenated derivatives of said groups are new compounds. The thioether halohydrins can be converted to epoxides. The process utilizing a radioactive energy source as a catalyst is new.
