Metallaboratranes: The M→B Dative Bond as a Ligand Activating Function in the Phosphaboration of Carbon Monosulfide

Abstract

The reaction of Na[H2B(mt)2] (mt = methimazolyl) with [RhCl(CO)(PPh3)2] proceeds via simple metathesis to provide the complex [Rh(CO)(PPh3){H2B(mt)2}]; however, with [RhCl(CS)(PPh3)2] C,C-phosphaboration of the thiocarbonyl ligand occurs, with formation of the novel cage complex [RhH-(PPh3){η2(C,S), κ2S′, S″-SC(PPh3)BH(mt)2}].
