Tert-butyl Nitrite is a metal-free radical initiator for aerobic cleavage of benzylic CC bonds in compressed carbon dioxide. It is also called 1,1-dimethylethylnitrite; 2-methyl-2-nitritopropane; alpha,alpha-Dimethylethyl nitrite; Nitrous acid, 1,1-dimethylethyl ester; Nitrousacid,t-butylester; Nitrous acid, t-butyl ester; Nitrousacid,1,1-dimethylethylester; Alpha,alpha-dimethylethylnitrite. It is colorless transparent or yellowish liquid with the relative density of 0.867, soluble in aether and ethanol etc. Not soluble in water. It has special odor and freely decomposable with exposition to light. It enjoys good developing prospect, widely applicable to pharmachemical industry, particulary to the manufacture of the important intermediates of new anti-cancer drugs.
