Others pivot from both bottom (like a hopper) and the side (like a casement). Also called Dual Action. Double-Hung Windows: Include offset upper and lower sashes, which can both move up and down in the frame. A window having two vertically sliding sash, each closing a different part of the window.
Reaction of sugar oxazolines with primary amines. In order to scrutinize the reaction pathway and structure of the reaction product, we started with a simple sugar oxazoline and a primary amine, carrying no other functional groups.
Carbonâcarbon bond forming reactions. bis(oxazoline) ligands have been found to be effective for a range of asymmetric cycloaddition reactions, this began with the very first application of BOX ligands in carbenoid cyclopropanations and has been expanded to include 1,3-Dipolar cycloaddition and Diels-Alder reactions.
