t-BuNO二聚体在不同溶剂中裂解机理的研究

STUDY ON CLEAVAGE MECHANISMS OF DIMER (t Bu) 2NO IN SEVERAL SOLVENT PHASES

本文利用１ＨＮＭＲ，ＵＶ－Ｖｉｓ方法，研究了ｔ－ＢｕＮＯ二聚体在有机溶剂及水溶液中的裂解反应产物，分析了其反应的动力学，提出了在非极性的有机相中ｔ－ＢｕＮＯ二聚体为均裂反应，而在极性的水相中为均裂和异裂同时进行的竞争反应。

In this paper,we studied the cleavage products of dimer t BuNO in aqueous and organic solutions using method of 1HNMR and UV Vis,analyzed the reactive kinetics,put forward that dimer (t Bu) 2NO homolytically cleavaged in nonpolar organic solution,and that dimer (t Bu) 2NO homolytically and heterolyticall cleavaged in a competitive manner in polar aqueous solution.
