CATALYTIC CARBONYLATION OF THREE AND FOUR MEMBERED HETEROCYCLES |
摘要 |
Epoxides, aziridines, thiiranes, oxetanes, lactones, lactams and analogous compounds are reacted with carbon monoxide in the presence of a catalytically effective amount of catalyst having the general formula [Lewis acid]<z+>{[QM(CO)x]<w->}y where Q is any ligand and need not be present, M is a transition metal selected from the group consisting of Groups (4, 5, 6, 7, 8, 9) and (10) of the periodic table of elements, z is the valence of the Lewis acid and ranges from (1) to (6), w is the charge of the metal carbonyl and ranges from (1) to (4) and y is a number such that w times y equals z, and x is a number such as to provide a stable anionic metal carbonyl for {[QM(CO)x]<W->}y and ranges from (1) to (9) and typically from (1) to (4). |
