## Abstract The chemistry of the highly substituted cyclobutanone derivative 2, which is easily accessible from 1, is dominated by the steric hindrance caused by the substitutents: Reduction with hydride reagents and nucleophilic additions with methyllithium are less stereoselective than correspond
The transition metal complex promoted isomerization of trans-bicyclo[4.1.0]hept-3-ene to cis-bicyclo[4.1.0]hept-3-ene

Derivatives of trans-bicyclo[4.1.0]hept-3-ene with chlorine and bromine substituents the 7 position were synthesized and their thermal rearrangements were examined. Thermolysis of the dichloride leads to the formation of the cis-fused isomer, while heating the dibromide results in ring-expanded prod
7-Methyl-frans-bicyclo[4LO]hept-3-ene has been synthesized and the thermal and transitionmetal-complex promoted rearrangements of trans-bicyclo[4.1.0]hept-3-ene, 7-methyl-franr-bicyclo[4.1.0]-hept3-ene, and 7,7-dimethyl-tranr-bicyclo[4.l.O]hept-3-ene have been compared.
