Resumen:
This work describes the reactions of [(µ-H)M 3 (CO) 9 (CCSiMe 3 )] (M = Ru, Os) with phosphines L (L = PMe 3 , PMe 2 Ph, PMePh 2 , and PPh 3 ) which produce zwitterionic compounds [(µ-H)M 3 (CO) 9 (HCCPR 3 )] where cleavage of the C[sbnd]Si and formation of C[sbnd]P bonds occurs. In the case of the ruthenium derivatives, CO substitution also occurs. Spectroscopic and structural characterization of the products is described. A theoretical analysis was carried out in order to understand the transformation pathway in the formation of the zwitterionic compounds. © 2019 Elsevier B.V.
