Reactions of Complex Ligands, XI: Stereoselectivity of the Insertion of Ynamines into the Chromium Carbene Bond: First Step of a Two‐Step Synthesis of Indanone and Indenone Derivatives Pentacarbonyl[methoxymethyl(or phenyl)carbene]chromium ( 1, 2 ) reacts with 1‐(dialkylamino)‐acetylenes ( 3, 4 ) in a stereoselective way to give E ‐ and Z ‐pentacarbonyl(alkenylaminocarbene)‐chromium complexes ( 5 – 7 ) via insertion of the alkyne into the metal‐carbene bond. The thermolysis of pentacarbonyl[(diethylamino)‐ E ‐(β‐methoxy‐α‐methylstyryl)carbene]chromium ( 7a ) in n‐decane results in the formation of the tricarbonylchromium complexes of 2‐methyl‐1‐indenone ( 8 ) and trans ‐3‐methoxy‐2‐methyl‐1‐indanone ( 9 ).
