Abstract
New hydrazinic derivatives and the manufacture of them. More particularly, the invention relates to di-lower alkyl-aminophenyl-lower alkylene-hydrazines and 1- (di-lower alkyl-aminophenyl-lower alkylidene) -2- [5-lower alkyl-isoxalyl- (3) -carbonyl] -hydrazines and salts thereof, as well as the manufacture of them. The compounds of this invention can be represented by the following structural formula: **FIGURE** where R1 represents a lower alkyl radical, R2 represents a saturated aliphatic hydrocarbon radical and R3 represents hydrogen or the 5-lower alkyl-isoxazolyl- (3) -carbonyl radical.
