Abstract
Synthesis of 4-carboxyl, 5-amino pyrazole was performed in both W/O microemulsions and two-phase system in presence of a phase transfer agent. The micro-structure of used microemulsions was determined by self-diffusion NMR. The reaction was fast in surfactantless microemulsion, slower in microemulsion with an anionic surfactant and sluggish in two phase system.
