Chromium (aryl)(alkenyloxy)carbene complexes underwent intramolecualr cyclopropanation reactions under mild conditions. Evidence for the intervention of metathesis/readdition and for twist' addition followed by {beta}-hydride elimiantion/reductive elimination was obtained. Carbenes of this class, sufficiently stable to isolate, underwent facile photochemical intramolecualr cyclobutanone formation. Molecular structures were determined by {sup 1}H and {sup 13}C NMR spectroscopy.
