Synthesis and free radical addition reactions of tris[(phenyldimethylsilyl)methyl]tin hydride

摘要

The synthesis of the new bulky tris [(phenyldimethylsilyl)methyl] tin hydride (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 H-1, C-13, Sn-119, and Si-29 NMR characteristics are included. [References: 19]
