Direct synthesis of aromatics of jet fuel by integrating CO2-FTS and toluene alkylation reaction
Although considerable efforts have been made in CO2 hydrogenation to produce long-chain hydrocarbons through the CO2 Fischer-Tropsch (CO2-FTS) pathway, the selectivity of C8+ hydrocarbons is still low. This work reported a new strategy for the production

Benzylation of N-phenyl-2-phenylacetamide under microwave irradiation [PDF]
Journal of the Serbian Chemical Society, 2008 N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of phase-transfer catalysts.

Late‐Stage Functionalization of Peptides on the Solid Phase
Angewandte Chemie International Edition, EarlyView.Peptide modifications are essential to control pharmacodynamic and pharmacokinetic properties of peptide drugs. Consequently, strategies that allow for efficient and rapid incorporation of non‐canonical modifications into peptides in parallel formats are highly sought after.

Few Layer 2D Pnictogens (P & Sb) Catalyze the Alkylation of Soft Nucleophiles with Esters
, 2018 Group 15 elements in zero oxidation state (P, As, Sb and Bi), also called pnictogens, are rarely used in catalysis due to the difficulties associated in preparing well–structured and stable materials. Here, we report on the synthesis of highly exfoliated,
