Thermal Stability of the Adducts 23. The adduct from 1 -carbomethoxyazepine and tetracyanoethylene (23d, 200 mg., m.p. 165-167°) was refluxed in chlorobenzene (20 ml., b.p. 132°) for 3 hr. The adduct 23d, m.p. 163-166°, was quantitatively recovered by complete distillation of the solvent. Its identity was confirmed by matched infrared spectra.
2,4,6-Trimethylheptane (TMH), a model compound for polypropylene, was autoxidized at 100 and 120°; the kinetic behavior of the reaction was studied, and the major products of the reaction were identified. The synthesis of alcohols, formed as oxidation products (after reduction of the primary product hydroperoxides), is also described. Intramolecular propagation seems to be the dominant reaction pathway in TMH oxidation. The
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.
