<p>A process for the hydroformylation of less reactive olefins with hydrogen and carbon monoxide in the presence of a hydroformylation catalyst which has been modified by a ligand of formula L(OR<1>)(OR<2>)(OR<3>), wherein L represents P or As and R<1>, R<2> and R<3> are (dis)similar aryl groups provided that at least one of R<1>, R<2> and R<3> is a group <CHEM> a group <CHEM> wherein H<4> is an optionally fluorine-substituted hydrocarbyl group, R<5> is H or R<4>, R<6> is H or an inert substituent on the meta and/or the para position of the ring, X is oxygen or sulphur, n is 0 or 1, and R<7> represents a hydrogen atom or an inert substituent. Less reactive olefins such as limonene can be hydroformylated with very good results.</p> |
