Cloisite 15Aº nanoclay as an effective PTC for the epoxidation of hydroxyl terminated polybutadiene (HTPB)

Polímeros, 2014
A simple method is reported for the epoxidation of hydroxyl-terminated polybutadiene (HTPB) by using in-situ generated dimethyl dioxirane (DMD) as an oxidant and Cloisite 15Aº nanoclay as a phase-transfer catalyst (PTC).

Kinetics of the Epoxidation of Geraniol and Model Systems by Dimethyldioxirane

Molecules, 2004
The mono-epoxidation of geraniol by dimethyldioxirane was carried out invarious solvents. In all cases, the product ratios for the 2,3 and 6,7 mono-epoxides werein agreement with literature values.

Z‐Retentive Enantioselective Rh‐Catalyzed Hydroarylation of E,Z‐Dienes

Angewandte Chemie, EarlyView.
The Rh‐catalyzed hydroarylation of conjugated E,Z‐dienoates is found to proceed with high selectivity for addition to the E‐alkene unit. Mechanistic analysis of this Z‐retentive process points towards preferred binding of the E‐alkene unit to a Rh‐aryl species to give rise to the observed selectivity and that Rh‐enolate protonolysis to be turnover ...
