                                    Hexamethylene tetramine hydrotribromide is found to be superior to pyridine hydrotribromide when compared with the rate of reaction and chemoselectivity for the regioselective cyclisation of a number of ortho-cyclohexenyl phenols 1(a-j) to 3-bromo-2,4-propano-chromans 2(a-j).
