for the synthesis of naphthalene derivatives through reaction of o-alkynylbenzaldehydes and styreneoxides in the presence of molecular iodine was developed. The reaction involves Meinwald rearrangement of styreneoxides to form the corresponding aryl acetaldehydes. The enol forms of aryl acetaldehydes might undergo [4+2] benzannulation reactions with iodinated benzopyrilium ions, formed in situ from
