By contrast, the terminal aryloxides have much shorter Al-O bond distances [Ao,c = -0.215 (1) to -0.282 (5) A, average -0.229 A] than predicted based on purely 6-bonding. WebThe catalytic cycle involves sequential C–H oxidative addition, CO2 insertion into Rh–C(aryl) bond, and transmetalation. Among these steps, CO2 insertion is the rate-determining step. In addition to its role as a methylation reagent, AlMe2(OMe) can also serve as a Lewis acid to promote the CO2 insertion step. north carolina osha ets
