The hydroformylation of conjugated dienes, v aliphatic tertiary phosphines and p-substituted phospholanes as cocatalysts of the rhodium-catalysed hydroformylation of 1,3-dienes

Abstract The hydroformylation of conjugated dienes to dialdehydes by rhodium carbonyl/tert. phosphine catalyst systems is determined by the nature of the tertiary phosphine cocatalyst. The influence of some typical aliphatic phosphines and of P-substituted phospholanes on the bishydroformylation of butadiene-1,3 is reported.
