Abstract
A novel procedure for the reduction and pinacol coupling of aromatic aldehydes and
ketones mediated by titanocene(III)/Zn in water is described. The titanocene-catalyzed
version in sea water proved to be especially convenient for the reduction of aryl
ketones. Mechanistically, the reaction presumably proceeds via free-radical chemistry.
Key words
green-chemistry - radical reactions - titanium - water - zinc

In the absence of Zn, the red-brown color of a Cp2 TiCl2 solution in deoxygenated water became only yellow after ten hours stirring. When
we added Zn, however, the color of the solution immediately changed to green and,
after a couple of minutes, to blue.

Cp2 TiCl2 is not too expensive (10 g = 28.50, Aldrich catalogue), but Zn dust is considerably
cheaper (1 Kg = 21.70).
