Transition metal free, green and facile halogenation of ketene dithioacetals using a KX-oxidant system

A facile oxidative halogenation of α-oxo ketene dithioacetals is achieved by using a potassium halide and oxidant combination under transition metal free conditions at ambient temperature. Using this methodology, halogenated ketene dithioacetals are synth

Preparation method of pyrazole derivative (by machine translation)

The preparation method comprises the following steps: mixing an alkyne propyl alcohol derivative, a halogen source, an acid and a solvent, heating and reacting, and reacting to Meyer - Schuster generate the pyrazole derivative. Compared with the prior art, the preparation method disclosed by the invention has 91% the advantages of maximum yield, simple operation, mild conditions, high conversion rate, few byproducts and the like, and provides a brand-new synthetic method for construction of pyrazole compounds.
