The complexation reactions between bis-(pyrazolyl)alkane derivatives and some transition metal salts were investigated and twenty new transition metal complexes were synthesised. The X-ray structures of three nickel(II) adducts are described.

It was found that vinylpyrazoles react with thiols both according to ionic and according to free-radical mechanisms, with the formation of products of alpha- and beta-addition. Radical thiylation of 1-vinylpyrazoles is a convenient method of synthesis of pyrazoles with sulfur-containing substituents.
