Ionic liquids as phase transfer catalysts: enhancing the biphasic extractive epoxidation reaction for the selective synthesis of β-O-glycosides
(Pergamon-Elsevier Science Ltd, 2017-08)
Ionic liquids promoted the direct epoxidation of glycals acting as PTC. 1,2-anhydrosugars were prepared by the oxidation of glycals under biphasic conditions with dimethydioxirane generated in situ from oxone/acetone and ...
Efficient Routes to Racemic and Enantiomerically Pure (S)-BINOL Diesters
(Taylor & Francis, 2013-09-04)
A systematic study for esterification procedures to the synthesis of BINOL diesters is described. Reaction conditions with TFAA and 85% H3PO4 were selected as the best procedure to prepare enantiomerically pure (S)-BINOL ...
Allylic alcohol synthesis by gas-phase hydrogen transfer reduction of unsaturated ketones
(Elsevier Science, 2005-06)
The gas-phase hydrogen transfer reduction (HTR) of mesityl oxide (MO) with 2-propanol to selectively obtain allylic alcohols was studied on MgO. MO was converted directly to 4-methyl-3-penten-2ol (UOL1) or isomerised to ...
Three-phase mass transfer: theoretical development of the overall effectiveness factor for cylindrical geometries
(Springer, 2021-05-06)
This work presents a theoretical analysis for predicting the overall effectiveness factor (η) for cylindrical geometries in a three-phase catalytic reaction system. Implicit expressions for η, taking into account all the ...
