mixtures due to apparent addition of trichloromethide and dichlorocarbene. In general, the yields of gem-dichlorocyclopropanes increased with increasing alkyl substituents on the alkene substrates. A trend toward increasing yield of gem-dichlorocyclopropanes was also noticed with the following substituents on the alkene substrates: OP(O) (OR)2 < Halogen ≅ OC(O)R < OR ≅ NRC(O)R′. Evidence is presented
