Pinacol Coupling

McMurry Reaction

This reductive coupling involves two steps. The coupling is induced by single electron transfer to the carbonyl groups from alkali metal (see Pinacol Coupling), followed by deoxygenation of the 1,2-diol with low-valent titanium to yield the alkene.

The McMurry Reaction works well to produce symmetric products or rings:
