Use of C,N-chelated di-n-butyltin(IV) fluoride for the synthesis of acyl fluorides, fluoroformates and fluorophosgene

The essentially quantitative conversion of various chloroformates, acyl chlorides, methanesulfonyl chloride, 4,4′-dimethoxytrityl chloride and various phosgene precursors or derivatives to their fluorinated analogs using {2-[(CH3)2NCH2]C6H4}(n-Bu)2SnF is described.
