2,2-Dithiocarboxylation of a chromium co-ordinated 1,3 dithian. X-Ray crystal structure of fac-tricarbonyl(diethyl 1,3-dithian-2,2-bisdithiocarboxylate)chromium

Abstract

Reaction of [Cr(CO)₅{[graphic omitted]H₂}] with BuLi and CS₂(–100°C) followed by alkylation gives the title compound (1), the structure of which has been determined by X-ray crystallography and in which the two preferentially co-ordianated thioketonic sulphur atmos exercise a considerable trans influence compared with the sulphide sulphur donor atom.
