Figure 4. (A) Time course based on 2-aminobenzyl alcohol conversion in the reaction of 2-amino benzyl alcohol with ethanol on Ni-NiAlZr-LDO at 120 °C under ambient atmosphere; (B) Catalytic performance on Ni-LDO in reaction of 2-aminobenzyl alcohol and ethanol at 120 °C in 26 h; (C) Substrates screening for Ni-NiAlZr-LDO catalyzed synthesis of NETHQ derivatives. The data in parentheses are reproduced results. LDO: Layered double oxides; NETHQ: N-ethyl-THQ; THQ: 1,2,3,4-tetrahydroquinoline.
