ABSTRACT Improved reaction conditions for the electrophilic reaction between a free aliphaticamine and 1H-pyrazole carboxamidine have been discovered. The surfactant-like guanidine salts, which are often hard to work with, were obtained in decent yields with short reaction times, minimal workup, and high level of purity. GRAPHICAL ABSTRACT

Monoalkylguanidinium bis-trifluoromethane sulfonimides are highly efficient adsorbents for the sequestration of organic anions from aqueous solutions and display strongly enhanced adsorption properties compared to conventional imidazolium ILs.
Ultrasound-assisted synthesis of substituted guanidines using 1H-pyrazole-1-carboxamidine and S-methylisothiouronium sulfate under solvent-free conditions

We have investigated ultrasound-assisted synthesis of guanidine derivatives using 1H-Pyrazole-1-carboxamidine (PyzCA) and S-substituted isothiouronium sulfate (MeITU). The guanylations of several amines are promoted by ultrasound sonication under solvent-freeconditions, and proceed under mild conditions. It is of particular interest that the guanylations do not require bases in most cases.
