The synthesis of 2-aryl/alkyl benzofurans by intramolecular photochemical Wittig response is accomplished by photochemical response. You will discover less further by-items during the response and may be controlled when the response also fulfills the environmentally friendly chemical requirements, although the compound yield is relatively minimal in this response (Scheme four).108 https://beta-pheny72604.alltdesign.com/detailed-notes-on-3-fpm-49632261
