资源简介：
Silver and copper ethylene adducts and the silver carbonyl
complex of the tris(pyrazolyl)borate [HB(3,4,5-(CF3)3Pz)3]− (which is based on one
of the most acidic pyrazoles known) have been synthesized. 13C NMR resonance signals of metal-bound ethylene carbon atoms of [HB(3,4,5-(CF3)3Pz)3]Ag(C2H4) and [HB(3,4,5-(CF3)3Pz)3]Cu(C2H4) appear at δ 111.6 and 94.9, respectively.
The CO stretching frequency of the silver adduct [HB(3,4,5-(CF3)3Pz)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.
