Abstract Formation of 1: 1 adducts in the addition of tetrachloromethane to a terminal carbon- carbon double bond was investigated at 76-200 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 85% yields. Aliphatic 1, ...
