Alkoxide Synthesis from Methyl and tert-Butyl Nitrite on Cu(100)

Abstract

A one-step synthesis of adsorbed alkoxides from alkyl nitrites dosed on Cu(100) is illustrated using methyl nitrite (CH3ONO) to form methoxide (CH3O) and tert-butyl nitrite (t-C4H9ONO) to form tert-butoxide (t-C4H9O). Compared with an alternative, dosing CH3OH on an O-covered Cu surface, only minor differences in the concentration and local chemical environment of CH3O are evident. The potential energy profiles associated with the two synthesis methods are contrasted, and the key role played by the weak RO−NO bond is emphasized.
