Abstract

One of the most thoroughly investigated reactions in homogeneous catalysis is the hydroformylation of olefins. Recently, one of us1 found that the zwitterionic rhodium complex 1 is an excellent catalyst for this process, with high regioselectivity observed for the branched (eq 1) or linear (eq 2) aldehyde depending on the nature of the reactant. However, poor regiochemical control was found during attempts to apply the reaction to a,@- ...
