Abstract: Herein, we synthesized an asymmetric A2-A1-D-A1-A2 type small molecule nonfullerene acceptor (NFA), HCl-BTA3, by chlorination on one side of A1. The synergistic effect of the asymmetric structure and chlorination endows HCl-BTA3 with a large dipole… read more here.

DOI: 10.1055/s-0039-1690879
Abstract: A fast and highly enantioselective chlorination of 4-pyrazolones catalyzed by bis(oxazoline)–Cu(ClO4)2·6H2O complexes has been developed. Under the optimized conditions, a series of pyrazolones bearing stereogenic chlorine-attached carbon centers were obtained in moderate to high yields… read more here.
