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

日期:——
The atom efficient transesterification of phosphate esters with catalytic base was investigated using an isopropenyl leaving group, generating acetone as the only by-product. The reaction proceeds in good yields at room temperature, with excellent chemoselectivity towards primary alcohols. Mechanistic insights were obtained by obtaining kinetic data using in operando NMR-spectroscopy.
