eng	Oxidative additions: Reactivity of a C,N-chelated stannylene towards compounds containing E-Cl bonds (E = C, Si, Ge, Sn).	Organotin species containing the 2-(N,N-dimethylaminomethyl)phenyl- moiety as a C,N-chelating ligand (LCN) are studied since seventieth of the last century.1 Significant intramolecular contact between tin and nitrogen atoms is the typical phenomenon of this class of compounds. Organotin(II) compounds (stannylenes), can undergo an oxidative addition reactions as first demonstrated by Lappert, Power and coworkers in 1976.2 Our recent progress in the field of chemistry of the doubly C,N-chelated stannylene (LCN)2Sn, first prepared by Angermund,3 involves its reactivity studies towards various E-Cl (where E = C, Si, Ge and Sn) bond containing species.4 We have found that these reactions yielded the desired products of oxidative addition that can be subsequently oxidized by dioxygen. Thus, for example, the reaction of (LCN)2Sn with benzoyl chloride yielded a novel acyltin(IV) species (Scheme 1). Further details concerning the preparation, structural characterization and reactivity of these organotin(II/IV) species will be discussed.
