Pd2dba3/P(i-BuNCH2CH2)3N catalyzed one-potsynthesis of unsymmetrically substituted trans-4-N,N-diarylaminostilbenes and both symmetrically and unsymmetrically substituted N,N-diarylaminostyrene derivatives is reported. The procedure involves two or more palladium catalyzed sequentialcouplingreactions (an amination and an inter-molecular Heckreaction) in one-pot using the same catalyst system with
