Regioselective Hydroformylation of Enynes Catalyzed by a Zwitterionic Rhodium Complex and Triphenyl Phosphite
摘要:
The reaction of aliphatic 1-en-3-ynes with synthesis gas in the presence of the zwitterionic rhodium complex (eta(6)-C6H5BPh3)Rh--(+)(1,5-COD) and triphenyl phosphite affords formyl dienes in high stereoselectivity. This catalytic system provides a useful method for the hydroformylation of both nonfunctionalized and functionalized conjugated enynes under mild conditions, affording formyl dienes in moderate to good yields.
