Реферат: A process capable of the low temperature carbonylation of an acetylenically unsaturated compound with carbon monoxide in the presence of an allenically unsaturated compound using a catalytic system, which is at least tolerant of the allenically unsaturated compound, formed from a) a palladium compound; b) a protonic acid; c) an organic phosphine of form (I), wherein R1 is an optionally substituted aryl group; R2 and R3 are joined to form an optionally substituted cyclic moiety comprising at least one optionally substituted alkylene group.
