Abstract
Chemo- and regio-specific palladium catalysed four component cascade p rocesses, involving formation of 4 new bonds, initiated by oxidative a ddition of Pd(0) with aryl/heteroaryl iodides followed by sequential i ncorporation of CO(1atm), allene (1atm) and an S- or N-nucleophile [Ph SO2-or (RNTs)(-)] occur in good to excellent yield at 50 degrees C.
