A series of cyclobutanes substituted 1,2- by polyenes of increasing radical-stabilizing power has been investigated to test the proposition that stabilization energies obtained independently from apposite, cis,-trans geometric isomerizations can be succes

Synthesis of conformationally-restricted 2-alkenylcyclopropylcarbene-chromium complexes has been accomplished, and subsequent thermal ring-expansion reactions examined. Thermolysis of conformationally-restricted carbene complexes yielded products that suggest this unique ring-expansion reaction is very dependent upon conformational effects.
