摘要：

Caught in a pincer: A chiral, imidazolidine-derived NCN-type palladium pincer complex has been prepared using a ligand introduction technique. Single-crystal X-ray diffraction analysis of this complex showed a well-organized asymmetric sphere. The neutral palladium/chloride version exhibited significant catalytic activity for the reaction of nitroalkenes with malononitrile to give products in a highly enantioselective manner (see scheme).
