CARBONYLATION PROCESS USING PALLADIUM PHOSPHINE CATALYST

摘要

The invention relates to a process for the carbonylation of an olefinically or acetylenically unsaturated hydrocarbon compound by reaction with carbon monoxide and a hydroxy compound in the pres- ence of a catalyst system comprising a source of cationic palladi- um, a source of phosphine and a protonic acid, which reaction is carried out in the presence of a free radical inhibitor.
