temperature. Further reaction with alkyl halides led to functional unsymmetrically substituted alkyldiorganostannanes, R12R2SnH. Tin hydrides with an ω-unsaturated substituent were stable at room temperature. With a 4-pentyl chain, they underwent a specific cyclization process, giving a stannacyclohexane under radical reaction conditions. A tin hydride with a tin−silicon bond could also be prepared.
diorganostannanes的金属化- [R 1 2 SNH 2由二异丙基氨基锂,得到相应的(hydridodiorganostannio)lithiums,R 1 2 SnHLi,其分别稳定在低的温度。与卤代烷的进一步反应产生功能性不对称取代的烷基二有机锡烷,R 1 2 R 2 SnH。具有ω-不饱和取代基的氢化锡在室温下稳定。它们带有一个4-戊基链,经过特定的环化过程,在自由基反应条件下得到一个锡环己烷。也可以制备具有锡硅键的氢化锡。
