Abstract

Alcohols and/or aldehydes are prepared from olefins by cross-metathesis of olefins with alcohols having at least one double bond in the molecule and in which at least one hydroxyl is in the allyl position relative to a C.dbd.C double bond over catalysts of the formula (I) EQU XX.sup.1 LL.sup.1 Ru [sic].dbd.CR.sup.1 R.sup.2 (I) with optional subsequent hydrogenation and/or isomerization, R.sup.1 and R.sup.2 being hydrogen or C-organic radicals with or without a heteroatom, X [sic] and X.sup.1 [sic] being, independently, anionic ligands, and L [sic] and L.sup.1 [sic] being, independently, neutral electron donor ligands.
