A catalyst don’t appear in the overall stoichiometry of the reaction it catalyzes, but it must appear in at least one of the elementary reactions in the mechanism for the catalyzed reaction. 220000-87-3, Name is 4-Chloro-N-methylpicolinamide, molecular formula is C7H7ClN2O. In an article, author is Zhang, Shi-Qi,once mentioned of 220000-87-3, Formula: C7H7ClN2O.
Ligand-controlled phosphine-free Co(II)-catalysed cross-coupling of secondary and primary alcohols
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.
