A. Gansauer, PINACOL COUPLING OF AROMATIC-ALDEHYDES CATALYZED BY A TITANOCENE COMPLEX - A TRANSITION-METAL-CATALYZED RADICAL REACTION, Chemical communications, (5), 1997, pp. 457-458
A trinuclear complex derived from titanocene chloride and magnesium br
omide is an efficient catalyst for the pinacol coupling of aromatic al
dehydes; the 1,2-diols are obtained with good diastereoselectivity and
a wide variety of sensitive functional groups are tolerated.
