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 β,γ-unsaturated monoaldehydes with high chemoselectivity and regioselectivity. η3-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. Keywords: Rhodium vapour; Hydroformylation; Conjugated dienes; Catalysis; Unsaturated aldehydes
