To explore the influence of substituent groups on thermally induced curing, eight new bio-based benzoxazines containing different with electron negativity and volumes were synthesized. The thermal curing these was studied in detail. Combined reaction kinetics, simulation calculation Highest Occupied Molecular Lowest Unoccupied values, spatial electronic effects benzoxazine explored. It found th...

In this study, we report the successful synthesis of a novel Al-based MOF/polybenzoxazine nanocomposite by facile and green approach via thermally induced ring-opening polymerization (ROP). Structural thermal characterization synthesized was accomplished using FTIR, XRD, BET TGA, DSC techniques, respectively. The Al-MOF showed catalytic activity in ROP good stability compared to non-catalyzed s...

In the field of cobalt(II) porphyrin-catalyzed metallo-radical reactions, organic azides have emerged as successful nitrene transfer reagents. In the pursuit of employing ortho-YH substituted (Y = O, NH) aryl azides in Co(II) porphyrin-catalyzed nitrene transfer reactions, unexpected hydrogen atom transfer (HAT) from the OH or NH₂ group in the ortho-position to the nitrene moiety of the key rad...
