Photoresponsive supramolecular gels have aroused continuous attention because of their extensive applications; however, most studies utilize UV light, which inevitably brings about some health and environmental issues. The halogen bond is an important driving force for constructing supramolecules due to

Poly(2-alkyl-2-oxazoline) (PAOx) hydrogels are tailorable synthetic materials with demonstrated biomedical applications, thanks to their excellent biocompatibility and tunable properties. However, their use as injectable hydrogels is challenging as it requires invasive surgical procedures to insert the formed hydrogel into the

New theoretical and experimental results for the ultraviolet photodissociation dynamics of thionyl chloride (SOCl2) are presented and combined with existing data from a variety of sources in order to provide a unified view of the photodissociation dynamics of SOC12. Time-dependent

A simple, one-pot preparation of cyclic amines via efficient chlorination of amino alcohols with use of SOCl(2) has been developed. This approach obviates the need for the classical N-protection/O-activation/cyclization/deprotection sequence commonly employed for this type of transformation. The reaction pathways

Chlorosulfonation of 3-methyl[1,2,4]triazolo[4,3-a]pyrimidine with chlorosulfonic acid in the presence of thionyl chloride was studied. When triazolo[4,3-a]pyrimidines are used as substrates, the substitution occurs at C-6. Also the reactivity of the hydrazides (7) towards aldehydes, thioglycolic acid and amines were studies.
