A cobalt-catalyzed selective dioxygenation of styrenes with N-hydroxyphthalimide (NHPI) was developed using molecular oxygen as the terminal oxidant. Alcohol and ketone products can be selectively formed from identical substrates by catalyst control. The reaction was applicable to a broad range of styrenes and exhibited good functional group tolerance. It provided a method for preparation of 1,2-diol or α-hydroxyketone derivatives. (Figure presented.).

Atom- and step-economic oxo-azidation and oxo-hydroxyphthalimidation of styrenes have been developed under mild electrolytic conditions, respectively. Various valuable alpha-azido or hydroxyphthalimide aromatic ketones were synthesized efficiently from readily available styrenes, azides, and N-hydroxyphthalimides. Mechanism studies show that two different pathways involved in these two transformations.

Paragraph 0019-0021, (2020/09/12)
The invention relates to a method for preparing 2-(2-oxo-2-phenylethoxy) isobenzyl-1, 3-diketone, which comprises the following steps: adding phenylacetylene and N-hydroxyphthalimide into a reactor, introducing oxygen into the reactor, adding 1, 2-dichloroethane, carrying out magnetic stirring, and putting the reactor into an oil bath pot to react; transferring the obtained reaction liquid into aseparating funnel, adding dichloromethane and water for extraction, and collecting a crude product of an organic phase after reduced pressure distillation; and carrying out column chromatography separation on the obtained crude product by adopting a system in which the ratio of ethyl acetate to petroleum ether is 1: 10, so as to obtain a white solid product of 2-(2-oxo-2-phenethoxy) isobenzyl-1, 3-diketone. The synthesis method has the advantages of mild reaction conditions, simple technological process, no participation of catalysts and oxidants and the like.
