Abstract

The synthesis of a new class of 1,4-bis(diphenylphosphino)-1,3-butadiene was discussed. Catalyst mixtures based on 1,2,3,4-Ph4-NUPHOS were found to be superior to those based on BINAP, with activities of 6900 and 260 (mol of product) (mol of palladium)-1h-1 respectively. The applications in palladium catalyzed cross-coupling reactions were also discussed.
