and heating in aqueous solution, and also under the conditions of the Stevens rearrangement (with KOH powder and a small amount of methanol) dialkyl-(4-hydroxy-2-butynyl)(3-phenylallyl)ammonium bromides form dialkyl[4-(1-phenylallyl)-2,5-dihydro-2-furyl]amines. Rearrangement–cleavage reaction also occurs under the same conditions.
在两倍过量的KOH的作用下,在
水溶液中加热,以及在Stevens重排的条件下(使用KOH粉和少量
甲醇)二烷基-(
4-羟基-
2-丁炔基)(3-苯基烯丙基)
溴化铵形成二烷基[4-(1-苯基烯丙基)-2,5-二氢-2-
呋喃基]胺。在相同条件下也会发生重排-裂解反应。
