摘要:
The synthesis of double O,C,O-chelated diorganotin(IV) compound L2SnBr2 (1), where L is 2,6-(MeOCH2)(2)C6H3-, the precursor for the synthesis of Sn <- O intramolecularly coordinated organotin(IV) cations is reported. Treatment of compound 1 with SnBr4 yielded the double O,C,O-chelated diorganotin(IV) ionic pair [L2SnBr](+) [SnBr5 center dot THF](-) (2). Both compounds 1 and 2 were characterized by H-1, C-13, Sn-119 NMR and molecular structure of compound 2 was established by X-ray diffraction. (C) 2010 Published by Elsevier B.V.
