Název v původním jazyce

Activation of E-Cl bonds (E = C, Si, Ge and Sn) by a C,N-chelated stannylene

Popis výsledku v původním jazyce

The reactivity of (L-CN)(2)Sn (1) (where L-CN is 2-(N,N-dimethylaminomethyl)phenyl-) towards various substrates containing E-Cl bond(s) has been studied (E = C, Si, Ge and Sn). Alkyl chlorides like chloroform or dichloromethane reacts with 1 to form (L-CN)(2)SnCl2 and unidentified by-products in poor yields. The reaction of benzoyl chloride with 1 at low temperature yielded a thermally unstable product (L-CN)(2)Sn(Cl)-C(=O)Ph (2) which was isolated and characterized by both multinuclear NMR spectroscopyand X-ray diffraction techniques. The vicinity of the central tin atom in 2 reveals trigonal bipyramidal geometry. Attempts to oxidize 2 by dioxygen to give the corresponding organotin(IV) benzoate failed. On the other hand, the reaction of the in situprepared (L-CN)(2)Sn=O (synthesized by the reaction of 1 with dioxygen) with PhCOCl resulted in the formation of the desired organotin(IV) benzoate (L-CN)(2)Sn(Cl)C(=O) OPh (3). The reaction of 1 with Ph3GeCl yielded triphenylgermyl-subst
