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.

This paper describes a novel approach for the surface modification of a cation-exchange membrane, bearing sulfonate groups, by a cationic layer. The modification procedure involved the chlorosulfonation of the sulfonate groups of the base membrane with thionyl chloride, followed by
Physical chemistry chemical physics : PCCP, 7(2), 301-309 (2005-01-21)
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
Thionyl-chloride (TCl) is used in the manufacture of lithium batteries, producing SO2 and HCl fumes on contact with water. We report two cases of accidental TCl exposure resulting in lung injury that may vary from a relatively mild and reversible
