Morpholinobenzenes with up to four N-morpholino groups have been synthesized efficiently from the corresponding bromobenzenes via palladium catalyzed multiple aryl amination reactions. Surprisingly, hexabromobenzene (1) yielded selectively 1,2,4,5-(N,N,N,N)-tetra-(23) and 1,3,5-(N,N,N)-trimorpholinobenzene (14).
