摘要：

Dicarbonyl{tris(3,5-dimethylpyrazol-1-yl)hydridoborato}rhodium (1) activates cyclohexane or benzene solvents when purged in the dark with N2O at 25°C and 1 atm. Nitrous oxide induced activation of these solvents by [Ir(η-C5Me5)(CO)2] (2) requires higher temperature and pressure; in cyclohexane at 125°C and 50 atm the yield of [Ir(η-C5Me5)(H)(C6H11)(CO)] is 76% at 59% 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. © 1990.
