Abstract

The reactions of Pd–aryl complexes with diazo compounds N2CH–CH[double bond, length as m-dash]CHPh and N2CHPh allowed us to isolate the organometallic products formed right after the migratory insertion of a non-stabilized CHR carbene into the Pd–aryl bond. η3-Allylic and η3-benzylic palladium complexes were formed respectively. This is compelling experimental evidence for the key step in the palladium-catalyzed cascade transformations of diazo derivatives leading to multiple C–C or C–X bond formation.
