- Addition of trichloromethyl radicals to alkenes: The use of phosphites as hydrogen-atom donors in intermolecular radical reactions
-
Addition of trichloromethyl radicals (generated from BrCCl3 or CCl4) to a variety of alkenes in the presence of hydrogen-atom donors has been explored. The use of phosphites as hydrogen-atom donors was shown to provide a mild, novel and technically clean approach to trichloroalkanes.

- METAL-OXIDE INDUCED REDOX CHAIN ADDITION OF TETRACHLOROMETHANE TO A CARBON-CARBON DOUBLE BOND
-
Formation of 1:1 adducts in the addition of tetrachloromethane to a terminal carbon-carbon double bond was investigated at 76-200 deg C.The redox chain addition reaction with 1-octene, electron-deficient alkenes and unconjugated aliphatic dienes induced by catalytic amounts of copper(I) or copper(II) oxides in conjugation with diethylamine or diisopropylamine afforded the corresponding 1:1 adducts up to in 85percent yields.Aliphatic 1,3-dienes underwent redox chain 1,4-addition giving isomeric 1,1,1,5-tetrachloro-3-alkenes.
