The palladium (0)-catalyzed coupling reaction of lithium (a-carbalkoxyvinyl)( dicyclohexy1amido) cuprates and organic halides such as aryl, vinyl, and benzyl halides was investigated. The lithium (a-carbalkoxyvinyl)(di-cyclohexy1amido) cuprates were generated by conjugate addition of organo (dicyclohexy1amido) cuprates to a, P-acetylenic esters. The coupling reaction using a Pd (PPhJ4 catalyst proceeded at room temperature ...
