SYNTHESIS OF 1-n-ALKYL-3-METHYL- AND 1-n-ALKYL-3- PHENYL-5-PYRAZOLONES AND FORMYL DERIVATIVES

SYNTHESIS OF 1-n-ALKYL-3-METHYL- AND 1-n-ALKYL-3- PHENYL-5-PYRAZOLONES AND FORMYL DERIVATIVES

3-Methyl- and 3-phenyl-5-pyrazolones were alkylated and formylated. The phenyl derivative was less reactive towards alkylation. However in the formylation step 1-n-alkyl-3-methyl- and 1-n-alkyl-3-phenyl-5-pyrazolones showed no difference in reactivity. The alkylated products exist as 5-pyrazolones i...
