Abstract
Propiolactone undergoes facile oxidative addition to low-valent electron-rich Ir(I) complexes. (C8H14)Ir(PMe3)3Cl (1) yields the structurally characterized iridalactone mer-(CH2CH2CO2)Ir(PMe3)3Cl (2) by cleavage of the CH2-O bond. The reaction is first order in both the lactone and 1. A likely mechanism involves nucleophilic attack by a 16-electron iridium complex on the CH2-O carbon atom. The structure of 2 has been determined crystallographically [space group P2l/c; a = 13.184 (5) Å, b = 13.852 (2) Å, c = 12.761 (4) Å; β = 111.20 (5)°; Z = 4; R = 0.033 for 4882 reflections].
