Improved process of polymerizing a polar monomer with selected initiators and catalysts, the improvement consisting of having present a chain transfer agent having a pKa greater than 18 but less than 25 and containing at least one reactive hydrogen atom which terminates the growth of "living" polymer.
Copper-catalyzeddecarboxylative thiolation using molecular oxygen as the sole oxidant was developed. A variety of aromaticcarboxylicacids including 2-nitrobenzoic acids, pentafluorobenzoic acid and several heteroaromatic carboxylicacids undergo efficient...
