Abstract
An addition of dichlorocarbene generated by a phase-transfer reaction, to 3,4-dihydro-2-ethoxynaphthalene gave 7,7-dichloro-6-ethoxy-2,3-benzobicyclo[4.1.0]hept-2-ene, from which 4,5-benzocycloheptenone was derived in preparative yield. 2-Methoxy- and 2-ethoxynaphthalene were converted into 2-chloro-4,5-benzotropone in 33 and 66% yield, respectively, by treatment with large excess of ethyl trichloroacetate arid sodium methoxide.
