The Synthesis of 5,6-Disubstituted Bicyclo[2.1.1]hexenes and 3,5-Disubstituted Tricyclo[2.2.0.0^2,6]hexanes

Abstract

There are relatively few methods for synthesizing bicyclo[2.1.1]-hexenes and tricyclo[2.2.0.0^2,6]hexanes.¹ However, now that benzvalene (I), the highly strained structural isomer of benzene has become a readily available compound,² it is possible to prepare disubstituted compounds like II and III in a straightforward fashion.
