A catalyst system that can be used to achieve (a) preparation of allylic alcohols by rearrangement of the corresponding epoxide, when the allylic alcohol is a desired product; (b) subsequent reaction, e.g., selective oxidation, of the allylic alcohols obtained in step (a) to afford a desired product, e.g., alpha, beta-unsaturated carbonyl compounds; and/or (c) the ability to perform steps a) and b) in a one-pot process. In one embodiment, the catalyst system includes (i) at least one primary catalyst includes one or more homogeneous or heterogeneous, inorganic, organic or complex metal-containing compound, and (ii) at least one activator/modifier comprising at least one phenolic compound.
一种催化剂系统可用于实现(a)通过重排相应环氧化物制备烯丙基醇,当烯丙基醇是所需的产物时;(b)随后的反应,例如选择性氧化,将在步骤(a)中获得的烯丙基醇转化为所需的产物,例如α,β-不饱和羰基化合物;和/或(c)能够在一个锅中进行步骤a)和b)。在一个实施例中,该催化剂系统包括(i)至少包括一个初级催化剂的催化剂包括一个或多个均相或异相的、无机的、有机的或复杂的含金属化合物,以及(ii)至少包括一种苯酚化合物的活化剂/改性剂。
