Synthetic Methods and Reactions. 163. For Part 162 see: Olah, G. A., Wu, A., Bagno, A., Prakash, G. K. S. Synlett 1990, 596.
Carbon monoxide, carbon dioxide, methyl alcohol, formic acid, carbonyl sulfide and carbon disulfide are reduced to methane by ionic hydrogenation using sodium borohydride and superacidic trifluoromethanesulfonic acid. Experimental details are given and the mechanism is discussed.
