Aliphatic polyamides containing pendent allyl groups were prepared by anionic ring-opening copolymerization of -caprolactam with monomer 1, the substituted lactam 3-(3-propenyl)-2-azepanone. Copolymerization experiments revealed that up to 11 mol % of 1 was integrated successfully into these novel polyamides, which ranged in molecular weight from 27 to 72 kDa. Relative to the well-known commercial polyamide-6 (PA-6), the degree of crystallinity of the copolymers decreased with incorporation of functional monomer. Moreover, the pendent allyl groups afforded rapid access to numerous functional aliphatic polyamides, using photoinitiated thiol-ene chemistry, providing a pathway to cross-linked polyamide films and gels.

An extremely mild method for amide-cleavage by using the triazine-based benzylating reagent 4-(4,6-diphenoxy-1,3,5-triazin-2-yl)-4-benzylmorpholinium trifluoromethanesulfonate (DPT-BM), which spontaneously releases benzyl cation species when being dissolved at room temperature, has been developed. O-Benzylation of the amide with DPT-BM and the subsequent hydrolysis of the resulting intermediate benzyl imidate salt afford the corresponding amine and benzyl ester, which can be converted by hydrogenolysis into a carboxylic acid under neutral conditions. O-Benzylation proceeds depending on both steric and electronic factors around the amide group. Thus, some amides have been selectively cleaved over other amides. Furthermore, intramolecular chemoselective cleavage of an amide group in the presence of an ester group was achieved. Such selective hydrolytic reactions cannot be performed with Meerwein reagents as well as under acidic or basic hydrolytic conditions.
