Streszczenie

A novel reaction between 3- and 3,5-substituted pyrazoles with selenium dioxide proceeds with for-mation of bis(3R,5R0-1H-pyrazol-4-yl)selenides in high yield. On this basis, an efficient one-pot syntheticprocedure has been developed. In the case of the unsubstituted pyrazole a selenonium compound hasbeen obtained. The identity and structure of the isolated selenium derivatives have been confirmed byspectral methods and their molecular structures investigated by X-ray analysis
