2-benzylcyclohexane-1,3-dione

反応条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

実験手順: 1-benzyl cyclohexane-2,6-dione (17.25 g), p-toluenesulfonylhydrazine (16.52 g) in methanol (290 ml) was treated with concentrated HCl (1 ml) and left at room temperature for 48 hours. Evaporation of the solvent under reduced pressure and crystallization of the residue gave 1-benzylcyclohexane-2,6-dione mono-p-toluenesulfonylhydrazone (5 g) m.p. 172°-3° C. Evaporation of the solvent under reduced pressure and crystallization of the residue
