Abstract
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.
Key words
