Abstract:
Experimental data obtained point to the mixed and competitive heterogeneous–homogeneous catalytic effect of Si-containing compounds on the methylation reaction of some aromatic NH-heterocycles with methanol at 350°C without additional methylating reagents. The starting SiO2-containing material (quartz, Pyrex glass or silica gel) reacts with methanol at supercritical conditions to form in-situ tetramethyl orthosilicate (TMOS). Both solid SiO2 and liquid TMOS have demonstrated the pronounced and comparable catalytic effect
