Structural Elucidation and Quantitative Analysis of Hydrogenation Products of Anthracene by NMR Spectroscopy
Chinese Journal of Magnetic Resonance,2021,Vol 38,No. 02
Three product mixtures from the anthracene catalytic hydrogenation under different catalytic conditions were analyzed by nuclear magnetic resonance (NMR) spectroscopy. Dihydroanthracene, tetrahydroanthracene, symmetric octahydroanthracene, and asymmetric octahydroanthracene were successfully detected with diffusion-ordered spectroscopy (DOSY) and one-dimensional selective gradient total correlation spectroscopy (selTOCSY) techniques. The 1H and 13C NMR signals of dihydroanthracene, tetrahydroanthracene, and symmetric octahydroanthracene were assigned by 1H NMR, 13C NMR, DEPT135, 1H- 1H COSY, and 1H- 13C HSQC. The conversion of anthracene and selectivity of the products were calculated by quantitative 1H NMR (QNMR). The results demonstrated that NMR is a versatile and powerful tool to guide and optimize catalytic reaction conditions for increasing the selectivity of symmetrical octahydroanthracene. The present research provides a systematic NMR analysis scheme for catalytic hydrogenation of polycyclic aromatic hydrocarbons.
