synthesis of the new bulky tris[(phenyldimethylsilyl)methyl]tinhydride (9), tetrakis[(phenyldimethylsilyl)methyl]tin (5), and hexakis[(phenyldimethylsilyl)methyl]ditin (10) as well as some physical properties are described. The addition of hydride 9 to seven mono- and disubstituted alkynes under radical conditions indicates that these reactions take place with complete stereoselectivity. Full 1H, 13C
新的大体积三[[(苯基二甲基甲硅烷基)甲基]锡氢化物(9),四[[苯基二甲基甲硅烷基)甲基]锡(5)和六[[苯基二甲基甲硅烷基)甲基]二锡(10)的合成以及一些物理性质是描述。在自由基条件下将氢化物9加至七个单取代和二取代的炔烃表明这些反应以完全的立体选择性进行。包括完整的1 H,13 C,119 Sn和29 Si NMR特性。
