Sp. Chavan et Ak. Sharma, Use of FeCl3 and FeCl3 adsorbed on silica as efficient Lewis acid catalystin ionic Diels-Alder reactions of alpha,beta-unsaturated acetals, SYNLETT, (5), 2001, pp. 667-669
The efficiency of FeCl3 adsorbed on silica, as conventional Lewis acid cata
lyst in Diels-Alder reaction of alpha,beta -enals, enones including their a
cetals with 1,3-dienes is described.
