Sequential homobimetallic catalysis: an unprecedented tandem Pd(0)-catalysed deprotection ? Pd(ii)-catalysed heterocyclisation reaction leading to benzofurans

Abstract

We report here the first example of “sequential homobimetallic catalysis”: a transition metal catalyst with the metal in a certain oxidation state catalyses the deprotection of a functional group, which in situ undergoes a subsequent transformation catalysed by another complex of the same metal but in a different oxidation state.
