reported. The reaction proceeds via the cleavage of a carbon–hydrogen bond at the position ortho to an alkynyl group, and no additives are needed. Platinum complexes bearing other common ligands, such as phosphines and NHCs, failed to promote this reaction, highlighting the utility of the silylene ligand in this reaction.
据报道,铂-亚甲硅烷基络合物催化二苯乙炔衍生物的环二聚。该反应通过在炔基邻位的碳氢键裂解而进行,不需要添加剂。带有其他常见配体(例如膦和NHC)的铂络合物无法促进该反应,从而突出了甲硅烷基配体在该反应中的效用。
