When heated in refluxing benzene or toluene, α-diazo β-ketophosphonates 2, prepared in three steps from aldehydes or ketones, gave rise to functionalized cyclobutenones 4 or phenolic compounds 5. These products are formed by electrocyclisation respectively of a vinyl or dienylketene, resulting from a Wolff rearrangement.
当在回流的苯或甲苯中加热时,由醛或酮分三步制备的α-重氮β-酮膦酸酯2生成官能化的环丁烯酮4或酚类化合物5。这些产物是由沃尔夫夫重排分别通过乙烯基或二烯基烯酮的电环化而形成的。
