I need to know the mechanism of reaction of phenacyl bromide and potassium isothiocyanate to give 1,3-thiazolidone. I think rearrangement occur but how and why

Title: 2-iminocoumarin formation

I hope you don't mind my merging your two different topics.  You've been here a while, and should be acquainted with the Forum Rules{click} (http://www.chemicalforums.com/index.php?topic=65859.0), we want to see your attempt.   A quick check of your posts shows you've taken to 'shotgunning', just asking a question and why without showing any effort.  Often, no one answers your posts, so I'm left wondering why you still persist in asking questions that way.
