Dispiro[5,0,5,4]hexadeca-1,4,8,11-tetraene-3,10-dione and a lower homologue, prepared by oxidation of the appropriate diphenols, decompose in neutral alcoholic solutions to give benzylic ethers arising, apparently, from quinone methide intermediates.
Dispiro [5,0,5,4] hexadeca-1,4,8,11-tetraene-3,10-dione和较低的同系物,由适当的二
酚氧化制得,在中性醇溶液中分解生成苄基醚显然是来自甲基醌的中间体。
