A palladium-catalyzed asymmetric decarboxylative reaction of racemic γ-methylidene-δ-valerolactones with aryl isocyanates has been developed to give enantioenriched 3,3-disubstituted 2-piperidones.

South Africa’s Department of Mineral and Petroleum Resources (DMPR) has granted environmental authorisation for an underground mining right and related infrastructural activities to ASX- and JSE ...

The preparation of palladium-based catalysts with both high catalytic activity and hydrothermal stability currently appears as a critical topic in methane combustion. Herein, we propose a facile ...
