Cellulose alkoxy radicals

In general, alkoxy radicals generated in cellulose are stable as compared to carbon radicals. The carbon radicals readily undergo secondary termination reactions. Carbon radicals in vacuo have an affinity for recombination and hydrogen abstraction to stabilize themselves in the presence of oxygen, and they are transformed rapidly into hydroperoxide radicals to build up hydroperoxide. This rapid oxygenation reaction is further accelerated when excited oxygen is presented (S3). 

Commercially important is also the use of ceric salts, which can reduce alcohols to alkoxy radicals and enable grafting from cellulose and other surfaces with... 

The experimental evidence obtained has shown that the reactivity of the estos of the aromatic and aliphatic carboxylic acids under study in the reaction of alcoholysis with cellulose changes substantially with changes in the chemical constitution of the acyl radical. According to existing con<%ptions (52), the alcoholysis of esters in the presence of an alkaline catalyst at the rate-determining step involves the attack of the alkoxy ion on the carbon atom erf the carbonyl group in the case of...
