give substituted pyrroles, with the extrusion of molecular nitrogen; the triazole moiety isomerised to an alpha-imino diazo species, and the denitrogenative addition to nickel(0) was followed by the insertion of alkynes and reductive elimination.
在镍(0)/膦催化剂存在下,N-磺酰基-1,2,3-三唑与炔烃反应,生成取代的吡咯,并挤出分子氮;将三唑部分异构化为α-亚氨基重氮物质,然后向镍(0)中进行脱氮加成反应,然后插入炔烃并进行还原消除。
