How to convert tropidene in to tropilidene (1,3,5-cycloheptatriene) is to be shown. Concept introduction: Two successive Hofmann elimination reactions of with quarternary ammonium salt of tropidene will yield tropilidene. To show: How to convert tropidene in to tropilidene (1,3,5-cycloheptatriene). Answer: The conversion of tropidene in to tropilidene (1,3,5-cycloheptatriene) is given below. Explanation: Tropidene when treated with excess of methyl iodide yields a quartenary ammonium salt which undergoes Hofmann elimination when heated with Ag 2 O and water to produce N,N-dimethylcycloheptadiene. Methylation of the diene with excess of methyl iodide yields another quartenary ammonium salt which undergoes Hofmann elimination reaction to yield tropilidene. Conclusion: The conversion of tropidene in to tropilidene (1,3,5-cycloheptatriene) is given below.
