Mh. Habibi et S. Farhadi, Photoinduced decarboxylation of aryl-substituted carboxylic acids using HgO. A new photo-Kolbe reaction pathway, J CHEM R-S, (12), 1998, pp. 776-777
Photoassisted decarboxylation of several arylcarboxylic acids using HgO in
argon-saturated organic solvents at 25 degrees C gives dimeric products in
good yield via homocoupling of arylalkyl intermediates.
