Description
(I) technical field
The invention relates to an oxidation synthesis method of selenium-participated alkyne sulfone compounds.
(II) background of the invention
The alkynyl sulfone is a sulfone derivative with important synthesis application, and the excellent reaction activity is represented by a carbon-carbon triple bond, and a series of reactions such as addition, substitution, cyclization and the like can be carried out on the triple bond. Due to the special structure that alkynyl is connected with sulfonyl, the alkyne sulfone compound can be directly used as antibiotic or anticancer drug.
The synthesis method of the alkyne sulfone compound mainly comprises a elimination method, a substitution method, an oxidation method and the like. Nair et al, which uses aryl acetylene and arylsulfinate as raw materials, first produce an intermediate, alkene sulfone, under anhydrous and anaerobic conditions, catalyzed by a catalyst CAN, and then add potassium carbonate to reflux to obtain an alkyne sulfone product. The method has harsh conditions and expensive catalyst, and is easy to generate aryl acetylene coupling byproducts. Truce et al (1956) and Kabanya et al (1956) use alkynyl sulfur as raw material, and hydrogen peroxide and potassium hydrogen persulfate as oxidant respectively to obtain alkyne sulfur product, and both methods have low selectivity, and can obtain a part of sulfoxide product besides sulfone product.
At present, it is necessary to find a method for synthesizing the alkyne sulfone compound, which is green, high in selectivity, low in cost, simple in treatment and easy to operate.

in the formulae (I) and (II), R1 is phenyl or C 1～7 Alkyl or halogen substituted phenyl or C 3～8 R2 is C 1～10 Alkyl, phenyl or by C 1～7 Alkyl or halogen substituted phenyl.
Preferably, R1 is phenyl, 4-fluorophenyl and n-butyl; r2 is methyl, ethyl or propyl.
Further preferably, in an embodiment of the present invention, the alkyne sulfone compound represented by formula II is one of the following:
preferably, the mass fraction of the active ingredient Ru in the Ru/C is 5%.
Ru/C (5% (g/g) of Ru) is used in an amount of 0.5 to 2% (preferably 1%) of the amount of the substance of the compound represented by formula (I) based on the amount of the substance of Ru, and diphenyldiselenide is used in an amount of 0.5 to 2mol% (preferably 1 mol%).
The progress of the reaction of the present invention can be monitored by GC-MS, and the completion of the reaction of the compound (I) is regarded as a time point for judging the completion of the reaction, and the reaction time is usually 1 to 2 hours.

Compared with the prior art, the invention has the beneficial effects that:
(1) The invention provides a preparation method for oxidizing an alkyne sulfur compound into an alkyne sulfone compound with participation of selenium, which has the advantages of simple operation process, high selectivity, yield of 95 percent or more, simple subsequent treatment and capability of obtaining a pure product without complex separation and purification.
(2) The traditional method utilizes ruthenium tetroxide for oxidation, however, ruthenium tetroxide has the defects of unstable property, high toxicity, high price and the like, and has certain limitation; compared with the traditional method, the method takes water as a solvent, and uses sodium periodate to oxidize cheap ruthenium carbon to generate ruthenium tetroxide at normal temperature, so as to further oxidize the alkyne sulfur compound to synthesize the alkyne sulfone compound. Therefore, the method is more efficient, rapid, environment-friendly and mild.
