High-nuclearity ruthenium carbonyl cluster chemistry. 8: Phosphine activation, CO insertion, and deruthenation at a phosphido cluster - X-ray structures of [ppn][Ru 8 (μ 8 -P)(μ-CO) 2 (CO) 20 ] and [ppn][Ru 7 (μ 7 -P)(μ-η 2 -OCPh)(μ-PPh 2 )(μ-CO) (CO) 17 ]

Abstract

Reaction of the square antiprismatic cluster [ppn][Ru8(μ8-P)(μ-CO)2(CO)20] [ppn = bis(triphenylphosphoranylidene)ammonium] with triphenylphosphine proceeds by loss of one cluster core vertex, phosphine P-C cleavage, and CO insertion into the putative Ru Show more
