What exactly happens as a mechanism? What I thought was: The alcohol group gets protonated and forms a stable carbocation at it's tertiary position. This charge can now wander to the tertiary carbon next to it; but an H-Shift should not be possible. What is the mechanism here?
I believe the mechanism should be somewhat like this (after the formation of carbocation) -
It would account for the product shown, but I am not sure if it's correct. I feel it's more favourable for a dehydration to occur with the hydrogen from the ring itself (shown on the dash at the top) to form this -
This double bond is conjugated and more substituted, so I should have thought that this would be the major product.
