, p. 905 - 908 (2004)
A practical synthesis of ortho-dialkylchlorosilyl-functionalized triarylphosphanes has been developed. An X-ray crystal structure analysis of phosphane 3 unambiguously confirmed the constitution of the new phosphane functionalized chlorosilanes. It also showed an interesting P/Si interaction, which may render this compound a model for the early stages of the mechanism of SN2 nucleophilic displacement at silicon.

A new mode of bond activation involving M→Z interactions is disclosed. Coordination to transition metals as σ-Acceptor ligands was found to enable the activation of fluorosilanes, opening the way to the first transition-metal-catalyzed Si-F bond activation. Using phosphines as directing groups, sila-Negishi couplings were developed by combining Pd and Ni complexes with external Lewis acids such as MgBr2. Several key catalytic intermediates have been authenticated spectroscopically and crystallographically. Combined with DFT calculations, all data support cooperative activation of the fluorosilane via Pd/Ni→Si-F→Lewis acid interaction with conversion of the Z-Type fluorosilane ligand into an X-Type silyl moiety.

PROBLEM TO BE SOLVED: To provide a phosphine compound utilizable as a silane coupling agent usable as a precursor for forming a covalent bond with an inorganic oxide by introducing a silyl group having a leaving substituent to the phosphine compound.SOLUTION: The phosphine compound is represented by formula (1), wherein Rand Rare each independently an aryl group or an alkyl group; Y is an aryl group or an alkyl group; X, when Y is an aryl group, is one group selected from the group consisting of a halogen atom, an alkoxy group, a hydroxy group and an amino group, and when Y is an alkyl group, is one group selected from the group consisting of an alkoxy group, a hydroxy group and an amino group; and n is an integer of 1 to 3.
Spontaneous oxidative addition of σ-Si-Si bonds at gold

Gold can do it! The activation of disilanes at gold was observed experimentally and analyzed theoretically. Upon chelation with two or even only one phosphine donor, the oxidative addition of σ-Si-Si bonds proceeds readily at low temperatures. These results show an unexpected similarity between gold and the other late transition metals towards σ bond activation.
