Boualy, Brahim,Harrad, Mohamed Anouar,El Firdoussi, Larbi,Ait Ali, Mustapha,El Houssame, Soufiane,Karim, Abdellah
experimental part, p. 1295 - 1297 (2012/01/13)
Various transition metal acetylacetonates have proven to be efficient catalytic systems for the Kharasch addition of tetrachloromethane to alkenes under mild conditions, providing 1:1 adducts in up to 87% yield, based on internal standard. The nature of metal, solvent, temperature, olefin/CCl 4 ratio and the presence of nucleophilic co-catalysts were tested to evaluate the scope and limitation of the reaction.

The Kharasch reaction, or atom-transfer addition of polyhalogenated alkanes to alkenes is known to be catalyzed by a number of Ru(II) complexes. The easily prepared [RuCl2(PPh3)3] was used to investigate the reaction scope. A number of halogenated alkanes were added to a range of alkenes with good to excellent regioselectivities.

Tisserand, Steve,Bejot, Romain,Billaud, Célia,Li, De Run,Falck,Mioskowski, Charles
, p. 5177 - 5180 (2007/10/03)
CrCl2-mediated condensation of γ-chloro-gem-trichloroalkanes with aldehyde generates homoallylic alcohols through a hydride rearrangement followed by a Nozaki-Hiyama allylation.
Addition of tetrachloromethane to alkenes, catalyzed by Pt(II) complexes
Zazybin,Khusnutdinova,Osipova,Solomonov
, p. 734 - 738 (2007/10/03)
Platinum(II) complexes [dichlorobis(triphenylphosphine)platinum(II), dichlorobis(tri-m-tolylphosphine)platinum(II), dichloro(2,9-dimethyl-1,10-N, N′-phenanthroline)platinum(II), etc.] showed catalytic activity in addition of tetrachloromethane across the double bond in 1-hexene, 1-heptene, 1-octene, 1-decene, and cyclohexene. The stability of the platinum catalysts was evaluated by GLC, gas chromatography-mass spectrometry, and 31P NMR and IR spectroscopy; the kinetic relationships of the addition reactions were determined. A reaction mechanism involving formation of trichloromethyl radical was suggested. A correlation was revealed for the first time between the catalytic activity of platinum, palladium, and rhodium complexes and the capability of these complexes to generate hexachloroethane. 2005 Pleiades Publishing, Inc.
Addition of carbon tetrachloride to unsaturated compounds catalyzed by manganese, vanadium, and molybdenum complexes

, p. 350 - 357 (2007/10/03)
It was found that CCl4 can add to linear and cyclic olefins and dienes in the presence of manganese, vanadium, and molybdenum complexes. The effects of the olefin nature, temperature, reaction time, the nature of the catalyst central atom, and
Addition of α-polyhalides to olefins under mild reaction conditions, catalyzed by Mo(CO)6
Shvo, Youval,Green, Revital
, p. 77 - 83 (2007/10/03)
Mo(CO)6 was found to be an efficient pre-catalyst in the 1,2-addition reaction of α-polyhalides to various olefins. Significantly, the reaction was run under mild conditions, viz. refluxing acetonitrile, with satisfactory yields. Cr(CO)6/
The Fe0 promoted addition of CCl4 and CCl3Br to olefins
