| titleOfInvention | Catalytic dehydrogenation process for the preparation of 3,5-disubstituted pyrazoles |
| abstract | ABSTRACT OF THE DISCLOSURE There is provided a process for the preparation of 3,5-disubstituted pyrazoles which involves: (a) the reaction of a methyl ketone, such as acetophenone or an appropriate derivative thereof, with an appropriate aldehyde, such as benzaldehyde in the presence of base to form a 1,3-disubstituted .alpha.,.beta.-unsaturated ketone, such as chalcone or a substituted chalcone, (b) the acidification of said a,.beta.-unsaturated ketone, follow-ed by treatment of the acidified reaction mixture with hydrazine to form a disubstituted pyrazoline, and (c) the catalytic dehydrogenation of said pyrazoline to yield the desired 3,5-disubstituted pyrazole. |
