4-Sulfanyl-1,2,3-triazole as a Powerful Ligand in CuAAC to Synthesize 1,4-Substituted 1,2,3-Triazoles Under Solvent-Free and Low Catalyst Loading [PDF]
Molecules4-Sulfanyl-1,2,3-triazole (L1) accelerated the solvent-free CuAAC efficiently with low catalyst loading (0.1 mol% for common azides and 1 mol% for sulfonyl azides). L1 exhibited higher catalytic activity compared to 1,4-substituted 1,2,3-triazole without

Solvent‐Free Synthesis of Peptides [PDF]
Angewandte Chemie, 2009 A crush on sweetness ! A novel solvent-free methodology for the synthesis of peptides was developed: the coupling of an urethane protected N-carboxy anhydride (UNCA) of an aminoacid with another aminoacid derivative gave a protected dipeptide in very high yield under ball-milling conditions. The reaction is taking place in the solid state. This solvent-

Scalable solvent-free production of liposomes [PDF]
Journal of Pharmacy and Pharmacology, 2020 Abstract Objectives A major challenge faced with the manufacture of liposomes is the high volumes of organic solvents used during manufacturing. Therefore, we have implemented an organic solvent-free production method for drug-loaded liposomes and demonstrated its applicability with both aqueous core ...

Predicting the activity coefficients of free-solvent for concentrated globular protein solutions using independently determined physical parameters. [PDF]
PLoS ONE, 2013 The activity coefficient is largely considered an empirical parameter that was traditionally introduced to correct the non-ideality observed in thermodynamic systems such as osmotic pressure.

Solvent-free autocatalytic supramolecular polymerization [PDF]
Nature Materials, 2021 Abstract Solvent-free chemical manufacturing is one of the awaited technologies for addressing an emergent issue of serious environmental pollution. Here, we report "solvent-free autocatalytic supramolecular polymerization (SF-ASP)", where a phthalonitrile derivative with hydrogen-bonding side chains as the monomer is autocatalytically ...

Solvent‐Free Photobiocatalytic Hydroxylation of Cyclohexane [PDF]
ChemCatChem, 2020 AbstractThe use of neat reaction media, that is the avoidance of additional solvents, is the simplest and the most efficient approach to follow in biocatalysis. Here, we show that unspecific peroxygenase from Agrocybe aegerita (AaeUPO) can hydroxylate the neat model substrate cyclohexane.
