The reaction of [Cp*RhCl(Ph)(PR3)] (R = Ph or Me) with internal alkynes in the presence of NaBAr(F)4 affords the o-vinylaryl complex with a Rh-(vinyl CH) agostic interaction by way of the alkyne insertion followed by 1,4-rhodium migration, providing the first example of the 1,4-migration of a Rh(III) center.
