The oxidation of tetraphenylallene (1) with m-chloroperbenzoic acid has been reported. Under acidic conditions, 1-hydroxy-1,3,3-triphenyl-2-indanone (2) was isolated in 45% yield, along with benzophenone (3) and the m-chlorobenzoate of 2 as minor products. In the presence of sodium carbonate, the oxidation products were 2,2,4,4-tetraphenyloxetanone (6), 3, and 1,3,3-triphenyl-2,3-dihydro-5H-indene-2,5-dione (5). The prolonged oxidation of 2 with per ace tic acid yielded α,α-diphenylphthalide (9a). The alkaline hydrolysis of 2 induced ring cleavage to give o-benzhydrylbenzilic acid (15b), whereas acid hydrolysis in ethanol or methanol gave the corresponding ethers, 16a and 16b respectively.
据报道,四苯基烯(1)与间氯过氧苯甲酸氧化反应在酸性条件下分离得到45%产率的1-羟基-1,3,3-三苯基-2-茚满酮(2),同时还有苯甲酮(3)和2的间氯苯甲酸酯作为次要产物。在碳酸钠存在下,氧化产物为2,2,4,4-四苯基氧杂环丁酮(6)、3以及1,3,3-三苯基-2,3-二氢-5H-茚满-2,5-二酮(5)。用过氧乙酸长时间氧化2得到α,α-二苯基酞内酯(9a)。2的碱性水解引发环裂解生成邻苯二甲酰化苯甲酸(15b),而乙醇或甲醇中的酸性水解分别得到相应的醚,16a和16b。
