ΜΕΛΕΤΗ ΑΝΤΙΔΡΑΣΕΩΝ ΠΡΟΣΘΗΚΗΣ ΠΥΡΑΖΟΛΙΚΩΝ ΣΥΣΤΗΜΑΤΩΝ ΜΕ 1, 3-ΔΙΠΟΛΑ ΚΑΙ ΚΕΤΕΝΕΣ

STUDY OF THE REACTIONS OF PYRAZOLES DERIVATIVES WITH NITRILOXIDES, NITRILIMINESAND KETENES. NON AROMATIC METHYLENE- PYRAZOLES IN PRESENCE OF NITRILOXIDE AND NITRILIMINES UNDERGO STEREOSELECTIVELY 1,3-DIPOLAR CYCLOADDITION, IN PRESENCE OF DIPHENYLNETENE THE CORRESPONDING 1-DIPHENYL-ACETYL (3,3-DIPHENYL- 2-AROGLOXY-2-PROPENYYL)-4,4 DIMETHYL-S-METHYLENE-1H PYRAZOLES. AROMATIC TRIMETHYL-PYRAZOLES IN PRESENCE OF NITRILOXIDES UNDERGO AN ELECTROPHILIC ATTACK, IN PRESENCE OF DICHLOROKETENE PRODUCTS OF ATTACHING AT NITROGEN ARE OBTAINED, IN PRESENCE OF DIPHENYLNETENE PRODUCTS OF ATTACKING AT CARBON ARE OBTAINED. THE REACTION WITH DIMETHYLKETENE FOLLOWS BOTH WAYS. THE STRUCTURE OF THE NEW COMPOUNDS WAS ELUCIDATED ON THE BASIS OF THEIR SPECTROSCOPIC DATA (I.V., N.M.V., M.S) AND IN SOME CASES FROM CRYSTALLOGRAPHIC X-RAY ANALYSIS.
