The carbinol II obtained from benzylideneanthrone (I) and benzylmagnesium chloride is dehydrated by acetic anhydride to 9,10-dibenzylidene-9,10-dihydroanthracene (III) and by a mixture of p-toluenesulphinic and formic acids to 1-benzylidene-4-phenyl-2,3,6,7-dibenzocyclohepta-2,4,6-triene (IV). A series of analogs of III have been preapred analogously. The mechanistic implications of the ring enlargement
由亚苄基蒽酮(I)和苄基氯化镁得到的甲醇II通过乙酸酐脱水成9,10-二亚苄基-9,10-二氢蒽(III),并通过对甲苯磺酸和甲酸的混合物脱水成1-苄叉基-4-苯基-2,3,6,7-二苯并环庚-2,4,6-三烯(IV)。类似地预先制备了一系列III的类似物。讨论了环扩大的机械含义。
