✦ Synopsis

As part of a program initiated to promote our attention in the chemical and physical properties of the bicyclofl.l.OJbutane incorporated iu the cyclic conjugated framework such as (Ia) 1) and (~?ZJJ,~J we wish to report a synthesis of 3,4-bensotricyclo[4.1.0.02"Jheptene (1~) , a valence isomer of 1,2-bensotropilidene , and its thermal and transition metal complex tions. Although parent tricyclo14.1.0.0287 Jheptene (2) has been synthesized routes starting from 7,7-dibromobicyclo[4.l.OJhept-3-ene 3) and bensvalene, 4) appeared no report to date of the synthesis of the bensolog (ICJ.

Sumnary: 4-Acetoxytricyclo[4.1.0.02y7 ]hept-4-en-3-one (S), a valence isomer of 2-acetoxytropone, was synthesized. Upon heating in pyridine at 15O"C, 3 rearranged into 1-acetoxybicyclo[3.2.O]hepta-3,6-dien-\*-one (9); the mechanism of which was examined by means of deuterium labeling experTments. Re
