The alkylation reaction of benzene with methanol to produce toluene: Y-C and Y-CCs catalyst
Green Chemistry Letters and Reviews, 2018 The secondary reaction of toluene is difficult to be suppressed in benzene alkylation with methanol over conventional acidic zeolite catalysts. Moreover, the formation of coke yet remains a challenging problem.

Functionalized C3-Symmetric Building Blocks—The Chemistry of Triaminotrimesic Acid
Molecules, 2022 A series of C3-symmetric fully substituted benzenes were prepared based on alkyl triamino-benzene-tricarboxylates. Starting with a one step-synthesis, the alkyl triamino-benzene-tricarboxylates were synthesized using the corresponding cyanoacetates.
