An iminopyridine cobalt dichloride complex was synthesized and demonstrated as an effective precatalyst for hydrosilylation/cyclization of 1,6-enynes with silanes. Various functional groups such as amine, free aniline, ester, ether, cyano, halide, trifluoromethyl, and heterocycle were tolerated to afford a variety of silicon-containing compounds. The reaction could be scaled up to afford products on
合成了亚氨基吡啶二氯化钴配合物,并证明了其为有效的预催化剂,可用于将1,6-炔烃与硅烷进行氢化硅烷化/环化反应。容许各种官能团,例如胺,游离苯胺,酯,醚,氰基,卤化物,三氟甲基和杂环,以提供各种含硅化合物。可以按比例放大反应,以提供克级的产物,该产物可以进行进一步的衍生化。在副产物分析和氘代实验的基础上,提出了一种主要机理。
