The Theoretical Study on the Mechanism of [3+2] Cycloaddition Reactions between α,β-unsaturated Selenoaldehyde with Nitrone and with Nitrile Oxide

, 2020
The reaction mechanisms of [3+2] cycloaddition (32CA) between the α,β-unsaturated selenoaldehyde with nitrone and nitrile oxide were investigated theoretically using the molecular electron density theory (MEDT). Selenoaldehyde has two unsaturations which

Metal Catalysis Acting on Nitriles in Early Earth Hydrothermal Systems

Life, 2023
Hydrothermal systems are areas in which heated fluids and organic molecules rush through basaltic material rich in metals and minerals. By studying malononitrile and acetonitrile, we examine the effects of metal and mineral nanoparticles on nitrile ...

Selection of elastomeric membranes for the removal of volatile organics from water [PDF]

, 1993
A wide range of homogeneous elastomeric membranes has been prepared using dicumylperoxide as a general cross-linking agent. The membranes have been used for both equilibrium sorption measurements and steady-state pervaporation experiments to study ...
