Paragraph 0052; 0054-0055, (2021/05/19)
The invention discloses a synthesis method of a 4-substituent cyclohexanone liquid crystal intermediate, which comprises the following step: carrying out oxidation catalytic reaction on 4-substituent cyclohexanol under the action of trichloroisocyanide urea to obtain the 4-substituent cyclohexanone liquid crystal intermediate. The method is high in reaction selectivity, high in yield, environment-friendly, simple in post-treatment and suitable for industrial production.

A new and simple PdCl2/DMA catalytic system for the alcohol oxidation has been developed using molecular oxygen as the sole oxidant under mild conditions. The catalytic system could be reused for three runs without significant loss of catalytic activity. A variety of active and non-active alcohols were oxidized to their corresponding carbonyl compounds in good to excellent yields. Gas-uptake kinetics for the catalytic system was also investigated. The ca. 1:1 molar ratio of O2 uptake to product yield is observed, suggesting the in situ formation of H2O2.

, (2008/06/13)
The invention relates to a process for the preparation of cyclohexanones from the corresponding phenols by partial hydrogenation, characterized in that the reaction mixture obtained by means of the hydrogenation is treated with sulfonating agents before the isolation of the cyclohexanone.
