Carbon dioxide reduction to methylamines under metal-free conditions.

Angewandte Chemie (International ed. in English)

Blondiaux E, Pouessel J, Cantat T.
PMID: 25243949
Angew Chem Int Ed Engl. 2014 Nov 03;53(45):12186-90. doi: 10.1002/anie.201407357. Epub 2014 Sep 22.

The first metal-free catalysts are reported for the methylation of amines with carbon dioxide. Proazaphosphatrane superbases prove to be highly active catalysts in the reductive functionalization of CO2, in the presence of hydroboranes. The new methodology enables the methylation...
