Abstract

A new carbon(0) complex 2 with two different L ligands, a phosphine and a sulfoxide, was synthesized and fully characterized. This new type of carbone exhibits excellent coordination ability, in contrast to the related phosphine/sulfide-supported carbon(0) complexes. Several organometallic complexes were isolated and, of special interest, the ν_av (CO) value of Rh^I -dicarbonyl complex indicates that 2 has a donor capability superior to classical NHCs.

Keywords: carbon(0) complexes; ligand; phosphine; sulfoxide; σ-donor.
