Thermal rearrangement of diethylamino-5-(m-methoxyphenoxy)-pent-2-yne (3) gives 1-(m-methexyphenoxy)-pent-3,4-diene (14) in about 8% yield. Hydration of the latter yields 1-(m-methoxyphenoxy)-pentan-4-one (6), which has been synthesised by an unambiguous route. A mechanism of formation of the allene (14) from the amine (3) has been suggested.
二乙基氨基-5-热重排(米甲氧基苯氧基) -戊-2-炔(3)给出1-(米-methexyphenoxy) -戊-3,4-二烯(14以约8%收率)。后者产量水合1-(米甲氧基苯氧基) -戊-4-酮(6已经通过一个明确的路线合成)。已经提出了由胺(3)形成丙二烯(14)的机理。
