Hydroformylation of vinyl sulfones and sulfoxides catalyzed by a zwitterionic rhodium complex. A diastereoselective process
摘要:
The hydroformylation of unsaturated sulfones and sulfoxides catalyzed by eta6-C6H5B-Ph3Rh+ (1,5-COD) (1) was achieved in excellent yield and regiocontrol, with exclusive formation of branched-chain aldehydes. In the case of phenyl vinyl sulfoxide, evidence is presented for stereoselectivity in the reaction.
