Bicyclo[1.1.0]butane Carboxamides to N-Heterocycles via a Strain Release-Enabled Nickel(II)–Carbene Intermediate

Abstract We report the conversion of bicyclo[1.1.0]butane carboxamides into N-heterocycles via strain release, enabling the generation of a novel class of Ni(II)–carbene intermediate and utilizing it for Ni(II)–carbene alkyne metathesis reactions for cyclopropanation and [4+2] cy...
