一般說明

Copper(I)oxide is a weak base that can be used in nucleophilic substitution, decarboxylation, cyclocondensation, and 1,1-addition reactions. It can also be used to form carbenoid intermediates from diazo compounds and radicals from arenediazonium salts[1].

應用

Copper(I) oxide can be used as a catalyst to synthesize:
  • Ynones via solvent-free Sonogashira reaction[2].
  • N-Heteroaryl derivatives via cross-coupling of nitrogen heterocycles with halopyridines[3].
