Abstract
The chemistry of transition metal carbynes, LnM≡CR, has historically been dominated by species bearing hydrocarbyl or amino 'R' substituents, with other elements appearing only sporadically. In recent years carbynes and related 'C1' species bearing other main-group substituents, particularly heavier elements of the p-block, have begun to emerge. This review details the chemistry of heavier pnictogen-functionalised C1 ligands, MCARn (A = P, As, Sb, Bi; n = 0-3), including their syntheses, properties and reactivities, and how these are distinguished from more traditional carbyne complexes. Recent developments in the closely related phosphaisonitrile, cya-phosphide and cya-arside ligands, LnM(C≡A) (A = P, As), are also discussed.
