S. Caddick et al., An improved synthesis of bis(1,3-di-N-tert-butylimidazol-2-ylidene)palladium(0) and its use in C-C and C-N coupling reactions, J ORGMET CH, 617(1), 2001, pp. 635-639
A new, improved synthesis of [Pd{CN(Bu-t)(CH)(2)N(Bu-t)}(2)] (1) and its us
e as a catalyst in coupling reactions, including aminations, is presented.
An interesting side product formed in the synthesis of 1, [Pd(eta (3)-C4H7)
(CN(Bu-t)(CH)(2)N(Bu-t)}Cl] (2), is also discussed. (C) 2001 Elsevier Scie
