Epoxy resins based on the 1,2,3,4-tetrahydroquinoxaline and the 2,3,4,5- tetrahydro-1H-1,5-benzodiazepine ring systems

The synthesis and characterisation of novel polyfunctional N-glycidyl epoxies are reported. N,N?-Bis(3-chloro-2-hydroxypropyl)-1,2,3, 4-tetrahydroquinoxaline underwent condensation with formaldehyde at the 6- and 7-positions to provide a mixture of the 6,6?-methylene and 6,6?/7,7?-dimethylene condensation products and oligomers, which were readily converted to the corresponding epoxy compounds. The product composition depended on the molar ratio of formaldehyde employed in the expected way. Enriched 13C n.m.r. spectra indicated that condensation was not completely exclusive to the 6 and 7 positions, and this was confirmed by employing N,N?-bis(3-chloro-2-hydroxypropyl)-1,2,3,4-tetrahydro- 6-methylquinoxaline in the condensation reaction. The effect of some other substituents and a more limited exercise with the 2,3,4,5-tetrahydro-1H-1,5-benzodiazepine ring are also described. Mixed coupled systems were prepared by condensing N,N?-bis(3-chloro-2-hydroxypropyl)-1,2,3,4-tetrahydroquinoxaline in the presence of N,N-bis(3-chloro-2-hydroxypropyl)-3-chloroaniline and N,N-bis(3-chloro-2-hydroxypropyl)-3,5-dichloroaniline, and simple physical blends were prepared by mixing 6,6?-methylene[N,N?-(2,3-epoxypropyl)-1,2,3, 4-tetrahydroquinoxaline] with the corresponding dichloro and tetrachloro derivatives of bis[N,N-bis(2,3-epoxypropyl)-4-aminophenyl]methane. The glass transition temperatures and water absorptions of castings prepared from the diamine-cured epoxies are given. The effect of hygrothermal and oxidative aging on the interlaminar shear strength of the most promising systems as the matrix component in unidirectional carbon fibre reinforced composites showed no significant improvement over current high performance composites. The synthesis and characterisation of novel polyfunctional N-glycidyl epoxies are reported.

Persulfate-promoted oxidative C-N bond coupling of quinoxalinones and: NH -sulfoximines

The persulfate-meditated oxidative C-N bond coupling of the C-H bond of quinoxalinones and the N-H bond of NH-sulfoximines is reported. The reaction proceeds smoothly under transition metal-free conditions and provides good to excellent yields of sulfoximidoyl-functionalized quinoxalinone products under mild conditions. The optimized conditions were found to be suitable for a range of sulfoximine and quinoxalinone substrates. This reaction offers a new and convenient strategy to directly install the sulfoximine moiety into the C3 position of quinoxalinone.
