R3M. radicals (M=C, Si, Ge, Sn, P, O, S) to give the corresponding paramagnetic adducts. In the case of 9-methylenanthrone radical addition occurred selectively at the exocyclic carbon-carbon double bond even with Group IV B organometallic radicals for which attack at the carbonyl oxygen would give rise to thermodynamically more stable adducts. When irradiating solutions of 9-methylenanthrone a photoinduced
使标题化合物与一系列R 3 M.基团(M = C,Si,Ge,Sn,P,O,S)反应,得到相应的顺磁性加合物。在9-亚甲基蒽酮基团的情况下,即使在IV B族有机金属基团上,环碳-碳双键选择性地发生加成,其对羰基氧的攻击将产生热力学上更稳定的加合物。辐射9-甲基蒽酮溶液时,发生了光致自反应,导致形成了二聚体。根据测得的ESR光谱参数,讨论了加合物的结构,以及R n M基团对β-质子超细分裂常数的影响。
