摘要:α,β-Unsaturated aldehydes are useful products as such in agrochemistry, but also potential intermediates for the preparation of important insect pheromones and kairomones. Until now, primarily the thermodynamically more stable (E)-α,β-unsaturated aldehydes have been identified as useful intermediates in the production of conjugated diene pheromone compounds, however, their practical and cost-effective synthesis on an industrial scale remains challenging. The problem to be solved by the present invention is to provide a method for selective oxidation of alkenes to α,β-unsaturated carbonyls which can be further transformed into pheromones and kairomones preferably without isolation and significant loss of the existing stereochemical purity.

摘要:Hydroformylation of alkenes to aldehydes in the presence of a rhodium complex catalyst is improved by the addition of a novel bidentate ligand of the formula ##STR1## wherein R 1 , R 2 , R 1 ' and R 2 ' are organic radicals selected from alicyclic, aliphatic and aromatic groups of which at least one is preferably substituted with at least one electronegative moiety and the methylene groups are present at the trans-2,3 positions on the norbomane moiety. The invention also provides a novel method for producing the bidentate ligand and novel intermediate phosphine oxide and phosphinous acid compounds.
