英文摘要	dicarbonylsalicylaldoximatorhodium (rh(sox)(co)(2)) combined with phosphorous ligands exhibits high activity for hydroformylation of olefins under mild conditions. the reaction rate and regioselectivity strongly depend on the phosphorous ligands and substrate. in the case of styrene, the branched aldehyde is the major product, almost pure 2-phenylpropanal can be afforded at 1.0 mpa. in the case of 1-hexene, n-aldehyde is predominant over iso-aldehyde. diphosphine ligands are much more active than monophosphine ligands, but the latter give higher regioselectivity for n-aldehyde. increasing the co/h-2 ratio results in a decrease of reaction rate and the regioselectivity towards n-aldehyde, probably due to the formation of more hydridic lnrhh. these catalytic systems are inert for hydrogenation of olefins under hydroformylation reaction conditions, but isomerization of 1-hexene was found and it may be inhibited by an excess of phosphines.
