Ionic liquids based on different l-amino acids (glycine, l-valine, l-leucine, l-isoleucine, l-
histidine, l-methionine, l-tyrosine, l-tryptophan, l-arginine, and l-threonine) and different …

In the pharmaceutical industry, the unexpected appearance of crystalline forms could impact
the therapeutic efficacy of an Active Pharmaceutical Ingredient (API). For quality control, a …

The mechanochemical click coupling of isothiocyanates and amines has been used as a
model reaction to demonstrate that the concept of a solvent-free research laboratory, which …

The occurrence of tautomeric polymorphism in the Cambridge Structural Database (CSD)
was established to be very rare in a previous study by AJ Cruz-Cabeza and CR Groom …

Amorphous thioacetamide (TA) ice was prepared by deposition on a low-temperature
substrate in an ultrahigh-vacuum simulation chamber, exposing the sample to a beam of …

Performing reactions in the solid state offers the largely unexplored possibility of influencing
reactivity by manipulating the solid form of the starting reactants. In this work, we explore the …

A series of 22 salts and co-crystals of gentisic acid and pyridine derivatives were
synthesized and their crystal structures were studied by X-ray diffraction. The proton transfer …

This work presents a successful application of a recently reported supramolecular strategy
for stabilization of metastable tautomers in cocrystals to monocomponent, non‐heterocyclic …

N-Salicylideneaniline (SA) and its derivatives are known to possess chromism upon
exposure to external stimuli. Herein, we present mechanochemical synthesis of a series of …

Tautomeric isomerism is very important in DNA/RNA research, especially base-pair
mismatches. However, the tautomeric polymorph of anhydrous guanine (AG) composed of a …
