eliminated by the addition of acetyl bromide to the reaction mixtures. Under such conditions the reaction is of first order with respect to ether and of second order with respect to hydrogen bromide in toluene, chlorobenzene, or (presumably) in excess ether; of three-halves order with respect to both reactants in chloroform; and of first order with respect to both reactants in acetic acid. The significance of these results and their bearing on the mechanism of solvolysis of alkyl halides are discussed.

The tertiary amine (gramine) reacts with malonic ester in the presence of a small amount of the sodium derivative of the ester to yield ethyl -carbethoxy-ß-(3-indole)-propionate. However, the yield of alkylation product obtained from the amine is inferior to that obtained from the amine methiodide.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
