Mj. Verhoef et al., REDUCTIVE ETHERIFICATION OF SUBSTITUTED CYCLOHEXANONES WITH SECONDARYALCOHOLS CATALYZED BY ZEOLITE H-MCM-22, Chemical communications, (20), 1997, pp. 1989-1990
Zeolite MCM-22 is an active and regenerable catalyst for a remarkably
shape selective reductive etherification of cyclohexanones with bulky
substituents at the 4-position, employing secondary alcohols as reduct
ants.
