摘要：

A straightforward method of synthesis of heteroleptic tin (II) alkoxides stabilized by one intramolecular coordination bond was developed. Addition of one equivalent of dimethylamino ethanol to diamide Sn(N(SiMe3)(2))(2) (5) yields alkoxy-amido derivative Sn(OCH2CH2NMe2)(N(SiMe3)(2)) (2). Further addition of alcohol leads to corresponding heteroleptic dialkoxides Sn(OCH2CH2NMe2)(OR) (R = Me (6), Et (7), Pr-i (8), Bu-t (9), Ph (10)). Catalytic activity of tin (II) compounds in polyurethane formation was tested. (C) 2009 Elsevier B.V. All rights reserved.
