The treatment of allylic p-tolyl sulfones with a catalytic amount of [Pd(PPh3)4] gave the 1,3-rearrangement products in high yields. A convenient method for the preparation of α,β-unsaturated ketones using [Pd(PPh3)4] as a catalyst from the 1,3-rearrangement products, 2-tosylhomoallyl alcohols, is also described.
用催化量的[Pd(PPh3)4]处理烯丙基对甲苯基砜,以高产率得到1,3-重排产物。还描述了一种使用[Pd(PPh3)4]作为催化剂从1,3-重排产物2-甲苯磺酰高烯丙醇制备α,β-不饱和酮的简便方法。
