Abstract
Newly synthesized, air and moisture insensitive palladacycle [PdCl(L-H)] (L = (C6H5)(2-HOC6H4) CHNH(CH2)(3)SePh; a (N, Se, C-) ligand) shows high catalytic activity for the Suzuki-Miyaura coupling reaction of phenylboronic acid with aryl/heteroaryl chlorides/bromides (TON for aryl chlorides up to 9200) and is converted to similar to 8 nm size particles of Pd17Se15 (probably the real catalyst).
