eng	Reactivity of a C,N-chelated stannylene towards organotin(IV) halides.	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. Significant intramolecular contact between tin and nitrogen atoms is the typical phenomenon of this class of compounds [1]. Organotin(II) compounds (stannylenes) can undergo an oxidative addition reactions as first demonstrated by Lappert, Power and co-workers in 1976 [2]. Our recent progress in the field of chemistry of doubly C,N-chelated stannylene (LCN)2Sn (1), first prepared by Angermund [3], involves its reactivity 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, a versatile and facile synthetic procedure leading to the formation of some novel distannanes has been explored (Scheme 1). Further reactivity studies of 1 towards various organotin(IV) halides (BuSnCl3, Bu2SnCl2, LCN(n-Bu)2SnX and others) will be presented. Structural characterization of prepared compounds will be discussed in detail, too.
