Tributyl-(2-pentenyl)tins were readily prepared in high yield by hydrogenation of tributyl-(2,4-pentadienyl)tins with diazene generated from 2,4,6-triisopropylbenzenesulfonohydrazide. The terminal double bond was selectively hydrogenated in the conjugated diene system. The stereochemistry of the internal double bond was completely retained.
通过氢化三丁基-(2,4-戊二烯基)锡与由 2,4,6-三异丙基苯磺酰肼生成的重氮,很容易制备出高产率的三丁基-(2-戊烯基)锡。在共轭二烯体系中,末端双键被选择性氢化。内部双键的立体化学结构完全保留。
