Unusual fragmentation of CH₂Cl₂by an Ir(<scp>iii</scp>) centre bonded to a doubly metalated Tp^MsLigand (Tp^Ms= hydrotris(3-mesitylpyrazol-1-yl)borate)

Abstract

The Ir(III) compound Tp(Ms'')Ir(N2), that contains a pentadentate, doubly metalated 3-mesityl substituted tris(pyrazolyl)borate ligand, induces the cleavage of C-H and C-Cl bonds of CH2Cl2 to yield a highly electrophilic chlorocarbene Ir=C(H)Cl complex.
