PHOTOCHEMICAL REACTIONS OF N,N-DIALKYL α-OXOAMIDES ADSORBED ON SILICA GEL AND ALUMINA

The photochemical reactions of N,N-dialkyl α-oxoamides adsorbed on silica gel were similar to those in acidic methanol, which indicated that the acidity of silanol groups on the surfaces of silica gel played important roles. The photolysis of the amides on alumina resembled those in methanol. The results of the photoreactions also suggested the absence of strong constraint upon the molecular motions of the amides adsorbed on these adsorbents.
