Cesium Carbonate‐Mediated Cascade Cyclization for the Efficient Synthesis of Fused Benzo[ <i>b</i> ]naphthooxepinone Derivatives Open
An efficient base‐promoted synthetic approach has been developed for the synthesis of benzo[ b ]naphthooxepinones from (3‐(acetylphenoxy)prop‐1‐yn‐1‐yl)benzaldehydes. The transformation proceeds via a base‐mediated 7‐ exo‐dig cyclization, …

Enhancement of the mechanical properties of EPDM/NBR rubbers using nanosilica for seal applications Open
In this research work, we looked at how the different properties of acrylonitrile-butadiene rubber (NBR) and ethylene-propylene-diene monomer (EPDM) as seal materials were affected by the addition of various percentages of nanosilica. To e…
