deoxygenative homocoupling reaction of the allyl alcohol to give the corresponding 1,5-diene as a major product. In addition to the deoxygenative homocoupling product, the allyl amine into which aniline was introduced was also obtained by using 1,2-diphenylhydrazine in the reaction of 1,3-diphenyl-2-methylprop-2-en-1-ol. Oxovanadium(V)-catalyzed deoxygenative homocoupling reaction of benzyl alcohols could
证明了在肼衍生物存在下,氧杂钒(V)催化的醇转化。在VO(OSiPh 3)3存在下1,3-二苯丙-2-烯-1-醇与1,1-二苯肼的直接酰化反应继续使用作为催化剂的MS3A和作为脱水剂的MS3A,得到相应的酰化产物。相反,发现利用1,1-二甲基肼代替1,1-二苯肼可引起烯丙醇的脱氧均偶联反应,得到相应的1,5-二烯为主要产物。除了脱氧均偶联产物外,还通过在1,3-二苯基-2-甲基丙-2-烯-1-醇的反应中使用1,2-二苯基肼获得引入了苯胺的烯丙胺。还可以在1,1-二甲基肼的存在下进行氧钒(V)催化的苄醇的脱氧均偶联反应。
