Enehydrazines, 20: Pyrazolinium Betaines from 1,1‐Dimethylhydrazine and 3‐Phenylglycidic Esters Ethyl trans ‐3‐phenylglycidate and 1,1‐dimethylhydrazine give the trans ‐4‐hydroxy‐5‐phenyl‐pyrazolinium betaine 1a , whereas the cis ‐phenylglycidic ester forms the cyclic cis ‐betaine 1b . Some degradation reactions are described.
