Benzamide reacts with and or -NEt3 in boiling toluene to afford the amidato products 1a and 2(PPh3)4> 2a respectively as orange or red air-stable crystals.Parallel reactions with o-, m- and p-toluamides yield analogous products 1b-1d and 2b-2d.Carbonylation of 2(PPh3)4> in boiling toluene affords the dicarbonyl 2(CO)2(PPh3)2> 3.Banzamide also reacts with to yield the bis(benzamidato) complex 2(CO)2(PPh3)2> 4.A crystallographic study of 1a established a binuclear structure bridged by hydride, banzamidate(1-) and benzamidate(2-) ligands.
