The influence of intramolecular coordination and solvent effects on the formation and stability of α-stannylvinyllithium reagents RR′CC(Li)SnMe3 (R′ = H, alkyl, aryl) has been investigated; intramolecular coordination via a 5-membered ring is particularly effective. Mechanisms for the isomerisation and thermal decomposition of RR′CC(Li)SnMe3 are discussed, and multinuclear NMR data (119Sn, 13C and
研究了分子内配位和溶剂效应对α-锡烷基乙烯基锂试剂RR'CC(Li)SnMe 3(R'= H,烷基,芳基)的形成和稳定性的影响;通过五元环的分子内配位特别有效。讨论了RR'CC(Li)SnMe 3异构化和热分解的机理,并给出了这些物质的多核NMR数据(119 Sn,13 C和1 H)。
