A photochemical route to 2-alkenyl- and 2-ethynylbenzofurans
Sumathi,Balasubramanian
, p. 3775 - 3778 (2007/10/02)
Intramolecular cyclisation of 1,5-biradicals generated by irradiation of o-alkenyloxy and o-alkynyloxy-benzophenones led to a facile synthesis of 2-alkenyl-3-phenyl and 2-ethynyl-3-phenylbenzofurans.
