Modification of zeolite H–Y by dithiane oxides (2- R -1,3-dithiane 1-oxide; R =H, CH 3 , C 6 H 5 ) is shown to enhance significantly its activity for the acid catalysed gas phase dehydration of butan-2-ol. The rate enhancement is observed for catal

Modification of zeolite H-Y by dithiane oxides (2-R-1,3-dithiane 1-oxide, R = H, CH3, C6H5) is shown to enhance significantly its activity for the acid-catalysed gas phase dehydration of butan-2-ol. The rate enhancement is observed for catalysts that

In an earlier paper we have shown that R-1,3-dithiane 1-oxide adsorbed in zeolite Y is able to dehydrate the S enantiomer of butan-2-ol at a rate of up to 19 times greater than the R enantioner. Thus a heterogeneous enantioselective catalyst has been

The proton form of zeolite Y was modified with R -1,3-dithiane-1-oxide at a loading of one molecule per supercage to create a chiral acid catalyst. The enantiomeric discrimination of this catalyst was demonstrated using the dehydration of the separat

Zeolite Y modified with chiral sulfoxides has been found catalytically to dehydrate racemic butan-2-ol enantioselectively depending on the chiral modifier used. Zeolite Y modified with R -1,3-dithiane-1-oxide shows a higher selectivity towards conver

The main principles of using molecular sieve catalysts for intermediates and fine chemical synthesis are reviewed and critically discussed. Emphasis is placed on describing the role of the elementary steps. The role of the catalytic functions (acid-b

The incorporation of chiral sulfoxides 1,3-dithiane oxide, 2-methyl-1,3-dithiane oxide and 2-phenyl-1,3-dithiane oxide- into zeolite Y by incipient wetness is being studied as a system for heterogeneous enantioselective catalysis. The system is shown
