| titleOfInvention | Process for producing carbonyl hydrazones |
| abstract | This invention relates to a method for producing compounds of the formula (I) or their salts: n n n wherein each of R 1 and R 2 is hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, OR 3 , SR 3 , COR 3 , COOR 3 or cyano; n R 1 and R 2 may combine together with the adjacent carbon atom of ═CR 1 R 2 to form an unsubstituted or substituted cyclic ring; n each of R 4 and R 5 is hydrogen, unsubstituted or substituted alkyl, unsubstituted or substituted alkenyl, unsubstituted or substituted alkynyl, unsubstituted or substituted aryl, unsubstituted or substituted heteroaryl, NR 6 R 7 , OR 8 or SR 9 ; n R 4 and R 5 may combine together with the adjacent skeleton of C/N bond to form a heterocyclic ring; n which comprises rearranging compounds of the formula (II) or their salts: n n n wherein R 1 , R 2 , R 4 and R 5 are as defined above. |
