C–H activation of 2,4,6-triphenylphosphinine: unprecedented formation of cyclometalated [(P⁁C)Ir(III)] and [(P⁁C)Rh(III)] complexes

Author affiliations

Abstract

An unprecedented C–H activation of 2,4,6-triphenylphosphinine by Ir(III) and Rh(III) has been observed. Time-dependent 31P{1H} NMR spectroscopy gave insight into the cyclometalation reaction and the corresponding coordination compounds were characterized by means of X-ray crystallography. In contrast, 2,4,6-triphenylpyridine does not show any ortho-metalation, demonstrating a remarkable difference in reactivity between these two structurally related aromatic heterocycles.
