Recently I am researching about CATALYZED ALPHA-ALKYLATION; N-HETEROCYCLIC CARBENE; BETA-ALKYLATION; C-C; KETONES; COMPLEXES; AMINES; DEHYDROGENATION; QUINOLINES; PYRIDINES, Saw an article supported by the National Natural Science Foundation of ChinaNational Natural Science Foundation of China (NSFC) [21771131, 21971182]; Project of Scientific and Technologic Infrastructure of Suzhou [SZS201708, SZS201905]. Safety of Chalcone. Published in PERGAMON-ELSEVIER SCIENCE LTD in OXFORD ,Authors: Zhang, SQ; Guo, B; Xu, Z; Li, HX; Li, HY; Lang, JP. The CAS is 94-41-7. Through research, I have a further understanding and discovery of Chalcone
Cobalt(II) complexes (5 mol% Co) bearing phosphine-free N<^>N<^>N pincer ligands efficiently catalyze C-C coupling of secondary and primary alcohols to selectively form alpha-alkylated ketones with a good functional group compatibility using NaOH (20 mol%) as a base at 120 degrees C. The NH group on the N boolean AND N boolean AND N Co(II) precatalyst controls the activity and selectivity. This simple catalytic system is involved in the synthesis of quinolones via the dehydrogenative annulation of 2-aminobenzyl alcohols with secondary alcohols. (C) 2019 Elsevier Ltd.
