Terminal, electrophilic phosphinidene complexes (M=PR) are attractive platforms for PR-transfer to organic substrates. In contrast to aryl- or alkylphosphinidene complexes terminal chlorophosphinidenes (M=PCl) have only been proposed as transient intermediates but isolable example remain elusive. Here we present the transfer of PCl from chloro-substituted dibenzo-7λ3-phosphanorbornadiene to a square-planar osmium(II) PNP pincer complex to give the first isolable, terminal chlorophosphinidene complex with remarkable thermal stability. Os=P bonding was examined computationally giving rise to highly covalent {OsII=PICl} double bonding.
期刊介绍：
ZAAC is an international scientific journal which publishes original papers on new relevant research results from all areas of inorganic chemistry, solid state chemistry, and co-ordination chemistry.
The contributions reflect the latest findings in these research areas and serve the development of new materials, such as super-hard materials, electrical superconductors, or intermetallic compounds. Up-to-date physical methods for the characterization of new chemical compounds and materials are also described.
