Dehydration of cyclopentanol
Web(a) Propose a mechanism for the dehydration of cyclopentanol using $\mathrm{POCl}_{3}$ and pyridine. The first half of the mechanism, formation of a dichlorophosphate ester, is similar to the first half of the mechanism of reaction of an alcohol with thionyl chloride. Like a tosylate, the dichlorophosphate group is a good leaving group. WebConclusions : The results support that the acid-catalyzed dehydration of 2-methycyclohexanol was successful. The GC percentages support Sayzteff’s rule; the more highly substituted alkene was the major product. 1-Methycyclohexene formed 67.712% of the product mixture and 3-methylcyclohexene formed 32.288% of the product mixture.
