Copper(I) and silver(I) complexes of formulae [Cu(NCCH3)4]+[A]- ([A]- = [B(C6F5)4]- (1), {B[C6H3(CF3)2]4} - (2), [(C6F5)3B-C3H3N 2-B(C6F5)3]- (3), and [Ag(NCCH3)4]+[B(C6F 5)4]- (4) are examined with particular emphasis on the strength of their M-N bond and its influence on the catalytic performance of these complexes in cyclopropanation and aziridination. To examine the strength of the M-N interactions, vibrational spectra of the related hydrogenated and deuterated species [Cu(NCCH3)4]+, [Cu(NCCD3)4]+, [Ag(NCCH3)4]+, and [Ag(NCCD3)4]+ are also determined. It is found that the metal-nitrile bond strength is an important factor for the catalytic activity of the respective complexes.

Homogeneous catalytic processes mediated by silver(I) complexes are relatively rare. This work describes the synthesis and characterization of acetonitrile ligated silver salts with three weakly coordinating anions [B(C6F5)4]- [B{C6H 3(CF3)2}4]- and [(C 6F5)3B-C3H4N 2-B(C6F5)3]-. The silver cation is coordinated either by four or by two acetonitrile ligands. All examined Ag(I) complexes show catalytic activity in coupling reactions of terminal alkynes with aldehydes and amines.
