Isotope effects on fluorine chemical shifts induced by heteroatoms bonded covalently to a carbon atom bearing fluorine atoms were studied. For each compound, the isotope-induced chemical shifts 2delta19F(X) through two bonds were measured for the heteroatom (X = 29/28Si, 30/28Si

Since 1995, Me(3)SiCF(2)H has been widely believed to be an inefficient difluoromethylating agent, which requires harsh reaction conditions to cleave its rather inert Si-CF(2)H bond. However, it has now been found that, by using a proper Lewis base activator, Me(3)SiCF(2)H
