Intramolecular Conversion of a Five-Membered Iridacycle to a Three-Membered Counterpart by CO2 Extrusion.

Abstract

Thermolysis of the metallacycles la and lb in refluxing toluene for 24 hours results in loss of CO2 and the formation of a product characterized by the formal oxidative addition of the 16-electron Ir(I) metal fragment CpIrPPh3 into the nitrile triple bond, generating the kinetically very stable side-bonded nitrile complexes 2a and 2b, in high yield. An X-ray diffraction study was undertaken of 2a confirming its structure as that containing a Ir(III)-C=n metallacycle.
