Procedimiento

Cabiddu et al. describe in Journal of Organometallic Chemistry 136 139-146 (1977) two competitive reactions which occur by the treatment of 1,3-benzodioxole in hexane with n-butyllithium in diethyl ether/hexane at -10° C. After carbonation of the reaction mixture the authors detected the formation of 1,3-benzodioxole-4-carbonic acid, originated from the 4-lithium compound with a yield of 41% and in addition thereto pyrocatechol and n-nonane, as a result of cleavage of the ether bond with a yield of each 45% of theory.
