Abstract

In ethanol, hydrocarbonylation reactions of alkenes catalysed by triethylphosphine complexes of rhodium give alcohols as the products with low linear selectivity, whilst rhodium complexes of PPri3 or PBui3 give mainly aldehydes, again with low linear selectivity. Modelling the proposed acyl intermediates by studying [Rh (C (O) Me)(CO) m (L) 4− m](L= PPri3 or PBui3) shows that they exist as monophosphine species under the ...
