A large array of aryl and heteroaryl mesylates have been successfully employed as electrophiles in a Csp(2)-Csp(3) Suzuki-Miyaura cross-coupling with potassium ammonio- and amidomethyltrifluoroborates to afford the corresponding products in high yields.
Direct <i>N</i>-alkylation of sulfur-containing amines
efficient ruthenium-catalyzed method has been developed for the direct N-alkylation of sulfur-containing amines with alcohols, for the first time, by a step-economical and environmentally friendly hydrogenborrowing strategy. The present methodology features base-free conditions and broad substrate scope, with water being the only by-product. Moreover, this protocol has been applied to the synthesis of the
