Reaction with tsoh
WebStep-by-Step Solution Step 1: Reaction of alcohol with TsOH TsOH is used to convert alcohol into alkenes. It is known as “dehydration of alcohol” and it is regioselective. The products of the reaction are formed according to the Zaitsev rule. After the elimination of -OH and -H atoms, there would be two alkenes formed. http://chem.ucalgary.ca/courses/350/Carey5th/Ch17/ch17-3-4-2.html
