Abstract
A chromium carbene complex (2) bearing a 2-methylaziridine ring system on the carbene carbon atom easily undergoes a double diphenylacetylene and a single CO insertion reaction to give a 1-oxotetrahydroindolizine derivative (4), which has been fully characterized by X-ray analysis of its Cr(CO)3 adduct (3).Keywords
