Aryl cyanides add to norbornene and norbornadiene under nickel catalysis to give (2R*,3S*)-3-aryl-2-cyanobicyclo[2.2.1]-heptanes and (2R*,3S*)-3-aryl-2-cyanobicyclo[2.2.1]hept-5-enes in good yields with a general substrate scope. On the other hand, the reaction of an aryl cyanide with triethoxy(vinyl)silane gives a Heck-type arylation product, suggesting the arylnickelation pathway in the catalytic
芳基氰化物在镍催化下与降冰片烯和降冰片二烯加成得到(2R*,3S*)-3-芳基-2-氰基双环[2.2.1]-庚烷和(2R*,3S*)-3-芳基-2-氰基双环[2.2.1]庚-5-烯在一般底物范围内具有良好的产率。另一方面,芳基氰化物与三乙氧基(乙烯基)硅烷的反应产生 Heck 型芳基化产物,表明催化循环中的芳基镍化途径。
