Preparation of organic molecules with two or more unpaired electrons is relevant to the emerging field of organic High spin polyradicals based upon 1, 3-connected polyarylmethanes are especially promising; star-branched ($= 5) decaradical, dendritic polyradical with 31 sites for unpaired electrons, and stable (at ambient temperature) tri-and tetraradicals have been reported. 6-8 Typical procedure for generation of a polyradical ...
