Frontispiece: Dimensioning the Term Carbenoid

Frontispiece: Dimensioning the Term Carbenoid
Pedro J. Pérez, Ana Caballero
A carbenoid species consists of a tetrasubstituted carbon atom bearing a leaving group X and a metal–carbon bond, from which extrusion of X triggers the elimination/transfer of the CR1R2 unit. This is the case of the largely known Simmons–Smith reaction (based on Zn) or the more recent gold-based carbenoid LAuCH2Cl described by Echavarren and co-workers. In the context of metal-induced carbene transfer from a diazo compound, a clear distinction must be made between the transient carbenoid and metal–carbene intermediates. For more information see the Concept article by A. Caballero and P. J. Pérez on page 14389 ff.
