Abstract

The reaction of HB(NCH₂PPh₂)₂C₆H₄-1,2 with [OsCl(Ph)(CO)(PPh₃)₂] affords the boryl pincer complex [OsCl(CO)(PPh₃){B(NCH₂PPh₂)₂C₆H₄}]. This complex, and its ruthenium analogue were observed to undergo various reactions involving substitution of the chloride and triphenylphosphine co-ligands to give new complexes [MCl(CO)(CNC₆H₂Me₃){B(NCH₂PPh₂)₂C₆H₄}] (M = Ru, Os), [MH(CO)(PPh₃){B(NCH₂PPh₂)₂C₆H₄}] (M = Ru, Os) and [Ru(κ²-S,S′-S₂CNEt₂)(CO){B(NCH₂PPh₂)₂C₆H₄}]. The ruthenium complex [RuH(CO)(PPh₃){B(NCH₂PPh₂)₂C₆H₄}] was found to react with carbon disulfide and carbon monoxide to give the complexes [Ru(κ²-S,S′-S₂CH)(CO){B(NCH₂PPh₂)₂C₆H₄}] and [RuH(CO)₂{B(NCH₂PPh₂)₂C₆H₄}], respectively, the latter as an apparently interconverting mixture of cis and trans dicarbonyl isomers.
