Abstract

A Neutral, Chiral, Bis(imidazolidine)-Derived NCN-Type Palladium Pincer Complex with Catalytic Activity. -The well-organized asymmetric reaction sphere of the title complexes is employed to catalyze the asymmetric reaction of nitroalkenes with malononitrile. The catalytic activity of these complexes is considerably facilitated by formation of a hydrogen bond between the substrate and the N-H proton in the pincer complex. In some cases addition of NaHCO 3 as a base is helpful in improving the yield. -(ARAI*, T.; OKA, I.; MORIHATA, T.; AWATA, A.; MASU, H.; Chem. -Eur. J. 19 (2013) 5, 1554-1557, http://dx.
