A complete set of pnictocarbynes: [M([triple bond, length as m-dash]CAPh2)(CO)2(Tp*)] (M = Mo, W; A = N, P, As, Sb, Bi; Tp* = hydrotris(dimethylpyrazolyl)-borate)

Abstract

The first two complete series of pnictogen functionalised carbyne complexes, [M([triple bond, length as m-dash]CAPh2)(CO)2(Tp*)] (M = Mo, W; A = N, P, As, Sb, Bi; Tp* = hydrotris(3,5-dimethylpyrazol-1-yl)borate), have been prepared. The heavier analogues (A ≠ N) result from successive treatment of [M([triple bond, length as m-dash]CBr)(CO)2(Tp*)] with nBuLi and ClAPPh2 (A = P, Sb, Bi) or BrAsPh2 and include the first examples of arsino, stibino or bismuthino carbyne complexes.
