The dominant radical in single crystals of anhydrous ..cap alpha..-D-glucopyranose X-irradiated at 77 K, a C6 primary hydroxyalkyl radical, reorients slightly upon warming to approx. 200 K and converts to a C2 primary hydroxyalkyl radical upon warming to approx. 300 K. Annealing the sample at room temperature overnight results in several free-radical products, one identified as a C2 secondary hydroxyalkyl radical. The mechanisms of the free-radical reactions are discussed and compared to those postulated by using data from end-product analysis of irradiated crystalline ..cap alpha..-D-glucose.
