The effects of seven carboxylic acids, i.e., acrylic acid, maleic acid, tartaric acid, malic acid, succinic acid, and citric acid, on CaCO3 crystallization were studied using the unseeded pH-drift method along with a light-scattering technique. Experiments were started by mixing solutions of ...
Arylboronic acidOxidative couplingNickel-catalyzed decarboxylative coupling reactions between aryl alkynyl carboxylic acids and arylboronic acids were developed. When aryl alkynyl carboxylic acids were reacted with arylboronic acids in the presence of NiCl2(10 mol%), 2,2-bipyridine (20 mol%), Na2CO3(...
