Chloride attacked the metal in 2B, yielding [Ru(CO)2(η1-C3H5)Cl(PMe2Ph)2], 8, which then reformed 1. Lability of the Ru–HB bond trans to hydride allowed nucleophilic access to the metal in 6, with low-temperature formation of [Ru(η1-BH4)(CO)H(L)(PMe2Ph)2] (11, 12, 13, L = PMe2Ph, CO, 4-methylpyridine
