Study Reactions of acetylenic amine N-Oxide with reactive Halides

Abstract

A new acetylenic amine derived from cyclic secondary amines such as piperidine were synthesized , these amine were oxidized with m-chloroper benzoic acid to the corresponding N-Oxides. The acetylenic amine and its oxide were investigated through the study of their physical and chemical properties ,spectral analysis (IR and UV) in addition to the micro analysis of the elements(C.H.N). Aqueous hydrochloric and hydrobromic acids ethanolic hydrogen chloride from the monomeric halides(II) of the amine oxide. dioxan solutions of hydrogen chloride, hydrogen bromide and hydrogen iodide or aqueous hydro iodic acid yield the dimiric hydrohalides(III).The monomeric hydrochloride and hydro bromide are converted to the dimiric hydro iodide (IV) by treated with sodium iodide. Reaction of the amine oxide which is readily split by picric acid. A mechanism for the formation of all complexes (II-V) as well as an explanation for the formation of all types of hydro halides were presented .
