Dicarbonylrhodium (1) activates cyclohexane or benzene solvents when purged in the dark with N2O at 25 deg C and 1 atm.Nitrous oxide induced activation of these solvents by (2) requires higher temperature and pressure; in cyclohexane at 125 deg C and 50 atm the yield of is 76percent at 59percent conversion in 1 h.Abstraction of the CO ligand in these reactions is proposed to involve a metallacyclic intermediate (unobserved) formed by attack of N2O as a 1,3-dipolar reagent on the metal-carbon bond.
