Abstract

Dichloro adducts 4 derived from ketones 2 are crystalline compounds except those derived from ketones 2h, 2i and 2 j which are oily mixtures of isomers. The separation of these dichloro derivatives from the media allows elimination of byproducts such as ac-chloro ketones which appear during the chloroselenenylation of some ketones (for example 2 j and 2k, Scheme 4). The or-selanyl ketones 6 are thus recovered without any further ...
