Abstract:
Silver and copper ethylene adducts and the silver carbonyl complex of the tris(pyrazolyl)borate [HB(3,4,5-(CF(3))(3)Pz)(3)](-) (which is based on one of the most acidic pyrazoles known) have been synthesized. (13)C NMR resonance signals of metal-bound ethylene carbon atoms of [HB(3,4,5-(CF(3))(3)Pz)(3)]Ag(C(2)H(4)) and [HB(3,4,5-(CF(3))(3)Pz)(3)]Cu(C(2)H(4)) appear at δ 111.6 and 94.9, respectively. The CO stretching frequency of the silver adduct [HB(3,4,5-(CF(3))(3)Pz)(3)]Ag(CO) is significantly higher than that of free CO, but it appears at a region less sensitive to the ligand electronic effects of tris(azolyl)borate silver adducts.

In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
