Abstract

Copper(I) and silver(I) complexes of formulae [Cu(NCCH3)(4)](+)[A](-) ([A](-) = [B(C6F5)(4)](-) (1), {B[C6H3(CF3)(2)](4)}(-) (2), [(C6F5)(3)B-C3H3N2-B(C6F5)(3)](-) (3), and [Ag(NCCH3)(4)](+)[B(C6F5)(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.
