feasibility of the addition of CCl4 to linear and cyclic olefins and dienes in the presence of chromium and ruthenium complexes was established. The influence of water as a nucleophilic additive and the influence of the olefin nature, the catalyst central atom, and its ligand environment on the reaction selectivity and product yields were investigated. It was shown that the addition of water to chromium and
Trichloromethanesulphonyl chloride reacts with styrene to give 1-phenyl-1,3,3,3-tetrachloropropane and 1,3-diphenyl-1,5,5,5-tetrachloropentane, together with sulphur dioxide.

Metalation of acetic, butanoic, or 2-methylpropanoic acid with lithium diisopropylamide in tetrahydrofuran under argon gave the corresponding lithium acylate α-carbanions which reacted with carbontetrachloride at 20–25°C for 2 h to afford butanedioic acid or its 2,3-diethyl and 2,2,3,3-tetramethyl derivatives, as well as the corresponding α-chlorocarboxylic acids and chloroform.

various olefins. Significantly, the reaction was run under mild conditions, viz. refluxing acetonitrile, with satisfactory yields. Cr(CO)6 was also studied but found to be inferior relative to the Mo complex. It was assumed that the active catalytic species is (CH3CN)3Mo(CO)3, generated in situ. The polyhalides examined were CCl4 and ethyl trichloroacetate. Acyclic, as well as cyclicolefins, and dienes
