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.
