Acylcobalt salophens (2) undergo homolytic cleavage (Δ, sunlamp) producing acyl radicals (10) which undergo oxidative additions to activated carbon-to-carbon double bonds leading to enones and functionalised ring systems e.g. (3)→(4); (5)→(6); (7)→(8); (12)→(13); and (14)→(15).
酰基钴盐分子(2)经历均相裂解(Δ,日光),产生酰基基团(10),这些基团经过氧化加成到活性碳-碳双键上,形成烯酮和官能化的环系,例如(3)→(4);(5)→(6);(7)→(8);(12)→(13); (14)→(15)。
