Question 1

Please propose a plausible mechanism for the following transformation.

Question 2

Question 3

Answer to question 1

The given reaction is the conversion of (5-(1-hydroxyethylidene) cyclohex-1-enyl) (phenyl)methanone to 1-(3-(hydroxy(phenyl)methylene) cyclohex-1-enyl)ethanone. It can be accomplished by protonating the molecule using H3O+H3O+ . Using this, the carbonyl oxygen is protonated and the transfer of electrons from the adjacent position takes place. Finally, on deprotonation from the alcoholic -OH group produce the product 1-(3-(hydroxy(phenyl)methylene) cyclohex-1-enyl)ethenone. The reaction mechanism is shown below,
