Thermal cycloadditions of butadiene to the title furanones afford 1,2-adducts which are converted into 1,4-adducts whithout prior reversion to the initial reactants, probably through a common biradical intermediate for both processes.
丁二烯与标题
呋喃酮的热环加成反应生成1,2-加合物,在未转化为初始反应物之前就可能将其转化为1,4-加合物,可能是通过两个过程的共同双自由基中间体。
