Paragraph 0022, (2021/01/29)
The invention relates to a synthesis method of alpha-cyanobenzoxime sodium, which comprises the following two steps: step 1, reacting an alcohol (alcohol: sodium nitrite: acid = 1: 1-3.5: 1-5) solution and a sodium nitrite (alcohol: sodium nitrite: acid =
Silica-supported 4-OH-TEMPO/NOx: A novel and efficient catalyst for aerobic oxidation of alcohols

Silica-supported 4-OH-2,2,6,6-tetramethylpiperidyl-1-oxy/NOx (4-OH-TEMPO was immobilized on the surface of silica using the sol-gel method, and then it adsorbed NOx), as a heterogeneous catalyst, has exhibited good catalytic performance in alcohol oxidation. A broad range of alcohols were oxidized to their corresponding aldehydes or ketones with more than 99% selectivity and 99% conversion rate by such a catalyst system at room temperature in air. NOx not only acted as an electron bridge between O2 and 4-OH-TEMPO but also were conducive to the formation of the aldehydes as active component. A possible mechanism for oxidation of alcohols promoted by silica-supported 4-OH-TEMPO/NOx was supposed. [Supplementary materials are available for this article.

Alkyl nitrites were prepared in good to excellent yields by treatment of alcohols and thiols with triphenylphosphine/2,3-dichloro-5,6- dicyanobenzoquinone/Bu4NNO2 in acetonitrile. This method is highly selective for the conversion of primary alcohols to alkyl nitrites in the presence of secondary and tertiary alcohols and thiols.
