The synthesis of alkynylboranes RR′ B C C R ″1–3 and their reactions with various nucleophiles are described (R, R′= Me2N, Cl, alkyl; R ″= Me, Ph). Although these compounds can be looked upon as inorganic Michael systems, nucleophiles such as alcohols, amines, amides and various carbon nucleophiles attack exclusively at the boron atom (analogous to a 1, 2 attack). Thus, a convenient means of functionalization of ...
