The reaction of cyclopentadienyl ruthenium complexes of the type [RuCI(Cp)L1L2] (L-1,L- L-2 = PPh3, PMe2Ph, PMePh2; L1L2 = dppe; L1L2 = COD; L-1 = CO, L-2 = PPh3) with Licarb (Hcarb = 2-Me-1,2dicarba-closo-dodecaborane) gives two types of complexes, [Ru(H)(C5H4-carb)L1L2] or [Ru(carb)(Cp)L1L2], depending on the nature of the coordination set. The structures of [Ru(carb)(Cp)(PMe2Ph)2] and [RuCl(eta(5)-C5Me4H)(PMe2Ph)(2)] have been determined by single-crystal crystallography. The role played by the ligand set on the site of nucleophilic attack is discussed in light of the steric crowding and electronic density at the metal center.

Abstract

The reaction of cyclopentadienyl ruthenium complexes of the type [RuCI(Cp)L1L2] (L-1,L- L-2 = PPh3, PMe2Ph, PMePh2; L1L2 = dppe; L1L2 = COD; L-1 = CO, L-2 = PPh3) with Licarb (Hcarb = 2-Me-1,2dicarba-closo-dodecaborane) gives two types of complexes, [Ru(H)(C5H4-carb)L1L2] or [Ru(carb)(Cp)L1L2], depending on the nature of the coordination set. The structures of [Ru(carb)(Cp)(PMe2Ph)2] and [RuCl(eta(5)-C5Me4H)(PMe2Ph)(2)] have been determined by single-crystal crystallography. The role played by the ligand set on the site of nucleophilic attack is discussed in light of the steric crowding and electronic density at the metal center.
