Abstract

Flash vacuum pyrolysis of (1-isonaphthofuryl) methyl benzoate (6) at temperatures in the range 550–700° C and ca. 10− 2 torr gave methylenenaphthocyclobutenone (13), 3-ethynyl- 2-naphthaldehyde (14) and naphthocyclopentadienone (15). The mechanism for the formation of 13–15 is proposed to involve double migrations of the benzoate group into the isonaphthofuran ring.
