Sulfonamides are known to represent a class of medicinally important compounds which are extensively used as antibacterial agents. Hence, a series of new N,N-diethyl amide bearing sulfonamides (2a-k) were synthesized via amidation of easily prepared benzenesulfonamide precursors (1a-k). The chemical structures of all synthesized compounds were substantiated using spectroscopic means such as IR,...

The title compound, C(12)H(12)BrNO(2)S, was isolated after direct irradiation (hν 350 nm, hexa-ne) of a mixture of stereoisomeric sulfonamides containing a vicinal dibromide and a conjugated diene. This product is one of a group of substrates that has contributed to our understanding of the photoreactivity patterns of non-bridged sulfonamides. The crystal structure was determined from a non-mer...

A new bromoform reaction of tertiary amines with N,N-dibromosulfonamides or NBS/sulfonamides has been developed. A series of amidines were prepared with moderate to good yields via a Csp(3)-Csp(3) bond cleavage.
