A new one-pothydroaminovinylationreaction has been achieved for the synthesis of sulfonated and phosphonated enamines using the zwitterionicrhodium complex Rh+(cod)(η6-PhBPh3)together with a chelating phosphine ligand as the catalyst. E.g., hydroaminovinylation of MeSO2CH:CH2 in the presence of syngas and Me2CHNH2 gave MeSO2CMe:CHNHCHMe2 and byproduct MeSO2CH2CH2NHCHMe2. The regioand stereoselectivity
