Abstract :
{2-[(CH3)2NCH2]C6H4}(n-Bu)2SnF (1) reacts with various chloroformates, acyl chlorides, methanesulfonyl chloride, 4,4′-dimethoxytrityl chloride and phosgene precursors or derivatives to form fluorinated analogues. All reactions proceed rapidly and under mild conditions. The use of a catalytic amount of 1 and KF in toluene led to a relatively high yield of a selected fluoroformate.
