Reactivity of photophido-bridged heterobinculear complexes: site-selective carbonyl substitution by a hydride. Synthesis and structural characterisation of NEt4[H(CO)3Ru(µ-PPh2)Co(CO)3]
Abstract
The phosphido-bridged heterobinuclear compound (CO)4Ru(µ-PPh2)Co(CO)3(1) on treatment with NaBH4 affords, via site-selective CO displacement on the ruthenium atom, the anion [H(CO)3Ru(µ-PPh2)Co(CO)3]– which contains a terminal hydride cis to a µ-PPh2 group: the structure of the anion has been established by an X-ray diffraction study of the Et4N+ salt.
