One-pot hydrogen peroxide and hydrohalic acid induced ring closure and selective aromatic halogenation to give new ring-fused benzimidazoles
(American Chemical Society, 2015-05-19)
A new series of selectively dichlorinated and dibrominated five- to eight-membered-ring [1,2-a]-fused benzimidazoles and [1,4]oxazino[4,3-a]benzimidazoles are synthesized in mostly high yields of >80% using the reaction ...
RAFT polymerization in supercritical carbon dioxide based on an induced precipitation approach: synthesis of 2-ethoxyethyl methacrylate/acrylamide block copolymers
(Wiley, 2015-05-13)
A new controlled/living heterogeneous polymerization technique using RAFT in benign supercritical CO2 is described involving the formation of monomer-swollen seed particles by precipitation of macroRAFT agent prior to ...
