experimental part, p. 3378 - 3385 (2010/06/20)
Carbanions of 3-substituted-3-chloropropyl phenyl sulfones add to carbonyl groups of aldehydes to produce aldol type adducts that undergo 1,5-intramolecular substitution giving 2,3,5-trisubstituted tetrahydrofurans. The effect of substituents in the 3-pos

The reaction of 1-aroyl-2-arylsulfonylethenes 1 with different ratios of hydrazine hydrate lead to hydrazones, dimerized products and 2-pyrazolines. The reactivity of pyrazolines has also been studied by dehydrogenation, pyrolysis, nitrosation and acylation.
