摘要：

The hydroformylation of 1,3-butadiene, 2-methyl-1,3-butadiene and 1,3-pentadiene using rhodium vapour-mesitylene cocondesates as a catalytic precursor is reported. The reaction gives beta,gamma-unsaturated monoaldehydes with high chemoselectivity and regioselectivity. eta(3)-Butenyl complexes, derived from the addition of Rh-H species to the conjugated double-bound system, are likely to be intermediates, as suggested by deuterioformylation experiments.
