【 摘 要 】

Electrophilic heterocyclization of 2-alkenyllthioquinolin-3-carbaldehydes or 2-alkenylselenoquinolin-3-carbaldehydes 2 , 3 under the action of iodine or bromine non-regioselectively leads to the formation of fused quinolinium trihalogenides 4 , 5 . Type of the chalcogen atom does not affect regiochemistry of halogenation.
