The synthesis of novel stibenium cations and their catalytic application in cyanosilylation of carbonyl compounds have been described. Treatment of chlorostibine L1SbCl [L1 = 1,2-C6H4{N(CH2tBu)}2] (2) with 1 equiv. of AgOTf and AgSbF6 resulted in the formation of donor free L1SbOTf (3) and [L1Sb]+[SbF6]- (4), respectively. Among these three compounds, 4 exhibits excellent catalytic activity towards the cyanosilylation of aldehydes and ketones.
