Conjugated Carbon-Centered and Nitrogen Radicals by H. Fischer (auth.), H. Fischer (eds.)

By H. Fischer (auth.), H. Fischer (eds.)

Volume II/17 c is the 3rd a part of a complement to the pre- vious compilations II/1 and II/9 a-d2 on magnetic houses of unfastened radicals released in 1965 and 1977-1980, which lined the literature as much as 1975. because of the nonetheless very quick improvement of the sphere and the inclusion of latest sub- jects, the complement overlaying the interval 1975-85 needed to be break up into subvolumes, as a way to seem in quick succession. Togetherwith the ealier volumes, II/17 bargains an updated and accomplished surveyand a set of information on impor- tant chemical intermediates.
