    Favorskii type rearrangement of cyclic α-bromo ketones 2 is promoted by NiCl 2 in refluxing methanol, giving the rearranged carboxylic acid ester 3 in excellent yields. The reaction of 4-bromo-2,3,4,5-tetrahydronaphth [2,1-b]oxepin-5-one (5) and its regioisomer 8 with NiCl 2 in MeOH resulted in Favorskii rearranged carboxylic acid esters 6 and 9 respectively.
