Supramolecular complex of 1-methylcyclopropene with cucurbit[6]uril as efficient reagent for apples treatment

The study is dedicated to the development of novel techniques for the synthesis and analysis of supramolecular complex of 1-methylcyclopropene and cucurbit[6]uril, with a view of further development of new agricultural products, e.g. Oberigpro and others, for fruit and vegetable treatment. Synthetic procedures were significantly improved at all stages allowing time and feedstock saving, as well as process efficacy and ecological aspect enhancement. Robust analytical procedure for 1-methylcyclopropene assaying was developed with the use of high performance liquid chromatography and chemical derivatization of 1-methylcyclopropene. Moreover, the release of the active compound from the complex was considerably increased, and high complex stability under various conditions was shown. In general, the study performed allowed making Oberigpro one of the most effective products for practical application among the existing analogs, and paved the way for further development of new agricultural products with controlled action.

Applications of Selectfluor for the oxidation of Sulfides, urazoles and alcohols under the solvent-free conditions

: Selectfluor acts as a safe and efficient reagent for the oxidation of urazoles, alcohols and also sulfides via releasing the electrophile F under the solvent-free conditions. In room temperature, this reagent cannot oxidize the substrates alone and requires KBr as the catalyst. In the proposed mechanism, Selectfluor converts the Br- to the Br-F and the lone-pair electron of substrates attack to Br-F to perform the oxidation reaction. This procedure offers some advantages; for example short reaction time, simple work-up, good yield and matching with some green chemistry approaches.

[(bpy)CuSCF3]: A Practical and Efficient Reagent for the Construction of C–SCF3 Bonds

In this account, we summarize recent work on the direct introduction of the SCF3 group by using [(bpy)CuSCF3] as trifluoromethylthiolating reagent. A number of efficient and convenient strategies have been disclosed for the synthesis of trifluoromethylthiolated compounds, including trifluoromethylthiolation of aryl, alkenyl, and alkyl halides, and arylboronic acids. These reactions afford various trifluoromethyl sulfides in good yields.1 Introduction2 Synthesis of [(bpy)CuSCF3]3 Trifluoromethylthiolation of Aryl Halides4 Trifluoromethylthiolation of Alkenyl Halides5 Trifluoromethylthiolation of Alkyl Halides6 Miscellaneous7 Conclusion
