The kinetics and mechanisms of the reactions of Na+⋅(X) n= 0–3, X= water, ammonia, and methanol with CH3CN, CH3COCH3, CH3CHO, CH3COOH, CH3COOCH3, NH3, CH3OH, and CH3–O–C2H4–O–CH3 (DMOE) were studied at ambient temperature under different pressures. All of the switching (substitution) reactions proceed at near??collision rate and show little dependence on the flow tube pressure, the nature and size of the ligand, or the ...
