Arynes were found to insert into a carbonâtin bond of
alkynyl- and vinylstannanes in the presence of a catalytic amount of a
palladiumâiminophosphine complex to afford ortho-substituted
arylstannanes, which were convertible into a wide variety of
1,2-disubstituted arenes via carbonâcarbon bond forming
reactions.
发现芳炔在存在催化剂量的
钯-
亚胺膦复合物的情况下,可以插入炔基和
乙烯基锡化合物的碳-
锡键,生成邻位取代的芳基
锡化合物,这些化合物可以通过碳-碳键形成反应转化为多种1,2-双取代的
芳烃。
