A novel and highly efficient protocol has been developed for the regioselective synthesis of 2-iminothiazole derivatives with potential biochemical interest by the reaction of enaminones, potassium thiocyanate (KSCN), and N-bromo succinimide (NBS) under mild conditions. The reaction proceeds via the formation of α-bromo enaminones as a versatile intermediate followed by thiocyanation/intramolec...

Due to the importance of SCN-containing heteroarenes, developing novel and green synthetic protocols for synthesis compounds has drawn much attention over last decades. We reported here an electrochemical oxidative cyclization ortho-vinyl aniline access various benzoxazines. Mild conditions, extra catalyst-free oxidant-free system, good tolerance air highlight application potential this method.

Organothiocyanate and organoselenocyanate compounds are of paramount importance in organic chemistry as they key intermediates to access sulfur- selenium-containing compounds. Therefore, among the different synthetic pathways get SCN- SeCN-containing molecules, original methodologies using electrophilic reagents have recently been explored. This Minireview will showcase recent advances that mad...

the magnetically recoverable fe3o4 nanoparticle and the supported brønsted acidic ionic liquid 1-methyl-3-(3-trimethoxysilylpropyl) imidazolium hydrogen sulfate (fe3o4-il-hso4) were synthesized and used as efficient magnetic catalysts for the regioselective thiocyanation of aromatic and heteroaromatic compounds at room temperature in water: ethanol. this procedure provided the target thiocyanat...

Selectfluor™ F-TEDA-BF4 (1-chloromethyl-4-fluoro-1,4-diazoniabicyclo [2.2.2]octane bis(tetrafluoroborate) is not only one of the most efficient and popular reagents for electrophilic fluorination, but as a strong oxidant is also a convenient mediator or catalyst of several "fluorine-free" functionalizations of organic compounds. Its applications as a mediator in transformations of oxidizable fu...
