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.
The reactions between alkanes and chlorine or bromine. There is no reaction in the dark. In the presence of a flame, the reactions are rather like the fluorine one-producing a mixture of carbon and the hydrogen halide.The violence of the reaction drops considerably as you go from fluorine to chlorine to bromine.he reactions of the cycloalkanes are generally just the same as the alkanes, with the exception of the very small ones-particularly cyclopropane. The extra reactivity of cyclopropane. In the presence of UV light, cyclopropane will undergo substitution reactions with chlorine or bromine just like a non-cyclic alkane.
