Abstract
The cyclization ofα- andβ-(arylseleno)alkylcarboxylic acids in polyphosphoric acid was studied. It was found thatα-(arylseleno)alkylcarboxylic acids do not cyclize under those conditions in which cyclization of the analogousβ-(arylseleno)alkylcarboxylic acids does occur. A convenient method for the preparation of 2-methylselenonapthanone by the cyclization ofα-phenylselenopropionyl chloride is proposed.
