Tritylium salts have been used as Lewis acid catalyst in organic synthesis for a long time. In this work, we found that the Lewis acid catalytic activity of tritylium ions...

Stable and soluble high-molecular-weight copper(I) arylacetylide polymers were obtained by unusual means. Long enough side chain, electron-withdrawing ester groups and chloroform solvent in polymerization can together relate to the solubility...
