the synthesis of [2-(butylselanyl)phenyl]propynols and their application as substrates in intramolecular iodine-promoted nucleophilic cyclization reactions for the preparation of 2-acylselenophenes. [2-(Butylselanyl)phenyl]propynols were prepared by nucleophilicaromaticsubstitution reactions of 2-halobenzaldehydes with lithium butylselenolate followed by alkynylation of the carbonyl function with lithium
