The effect of a bis(proazaphosphatrane) ligand on the palladium-catalyzed direct α-arylation of nitriles with various aryl chlorides under mild conditions is reported. Comparisons of the catalytic properties of this ligand with those of three related mono(proazaphosphatrane)s under the same reaction conditions revealed that bis(proazaphosphatrane) displayed a synergistically enhanced activity. In the presence of the bis(proazaphosphatrane) ligand, ethyl cyanoacetate and primary as well as secondary nitriles were efficiently coupled with a wide variety of aryl chlorides that contained electron-rich, electron-poor, and electron-neutral groups.

Palladium complexes incorporating ligands based on a 1,3,5,7-tetramethyl-2, 4,8-trioxa-6-phosphaadamantanyl scaffold were used to catalyze the arylation of ethyl cyanoacetate, malononitrile, and various ketones. The products from these reactions can be el

The long-standing challenge of developing a general method for the title methodology is met for a broad range of aryl chlorides through the use of bicyclic P(iBuNCH2CH2)3N (1) as a bulky electron-rich ligand for palladium (see scheme, dba = dibenzylideneacetone).
P(i-BuNCH2CH2)3N: An efficient ligand for the direct α-arylation of nitriles with aryl bromides
You, Jingsong,Verkade, John G.
, p. 8003 - 8007 (2007/10/03)
A new catalyst system for the synthesis of α-aryl-substituted nitriles is reported. The bicyclic triaminophosphine P(i-BuNCH 2CH2)3N (1b) serves as an efficient and versatile ligand for the palladium-catalyzed direct α-arylation of nitriles with aryl bromides. Using ligand 1b, ethyl cyanoacetate and primary as well as secondary nitriles are efficiently coupled with a wide variety of aryl bromides possessing electron-rich, electron-poor, electron-neutral, and sterically hindered groups.

In order to develop efficient chiral derivatizing agents (CDAs) which can be obtained readily in optically active form, synthetic studies of α-cyano- α-fluorophenylacetic acid (CFPA) analogs, 3a-e and CFNA (14a), were made. Carboxylation of 6a-e obtained
