L. Jordi et al., FLUORIDE-ION IN GROUP-6 METAL-CARBONYL CHEMISTRY - AN UNEXPECTED PROMOTER OF CARBONYLATIVE INSERTIONS IN ORGANIC AND ORGANOMETALLIC ENYNES, Organometallics, 12(10), 1993, pp. 3795-3797
Ready carbonylative cycloadditions were observed in the protodesilylat
ion of trimethylsilyl)alkynyl)(diallylamino)carbene)metal complexes me
diated by fluoride ions. A study of the ability of this ion to activat
e the ''(CO)5M'' fragments for an efficient carbonylative insertion pr
ocess was carried out and extended to organic enynes.
