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.

Phenylenedimalonitrile and the analogues, which are key intermediates in the synthesis of TCNQ and the analogues, are prepared directly by the Pd-catalyzed reaction of diiodoarenes with malononitrile anion.

7,8-Dimethoxycarbonyl-7,8-dicyanoquinodimethane and 7,8-diethoxycarbonyl-7,8-dicyaniquinomethane were prepared succesfully as novel compounds.These two compounds homopolymerized readly under thermal, radical, and anionic conditions except for cationic one.Moreover, weak bases such as triethylamine, pyridine, and pyrrolidine were found to induce the homopolymerization.
