Phosgene-free preparation of primary carbamates and Boc-protection of amine using H2SO4-Silica under solvent free conditions [PDF]
An efficient and mild method for the preparation of primary carbamate from alcohols and phenols using sodium cyanate and Boc-protection of amine in the presence of H2SO4-Silica was demonstrated.

Crucial Role of Oxidation for the Prebiotic Peptide Elongation Promoted by Carbonyl Sulfide
The prebiotic activation of amino acid (AA) into peptides via N‐carboxyanhydride (NCA), promoted by carbonyl sulfide (COS), cannot proceed without an oxidizing step (enabling better leaving groups than sulfur dianion). While being efficient even at mild pH the prebiotic scope of COS promoted activation of AA, it is however limited because side ...

Synthesis of Lewis Acid‐Base Adducts Between PCO− and Group 13 Lewis Acids
Lewis acid–base adducts [Na(18c6)(L)][PCO(EMe3)] (L = THF or 1,4‐dioxane; E = Ga, In) were obtained from the reactions of [Na(18c6)PCO] and trimethyltriels (EMe3 (E = Ga, In) and examined by NMR spectroscopy, IR spectroscopy, elemental analysis, and X‐ray structure analysis.
