One-pot synthesis of 1,3,4-thiadiazoles using Vilsmeier reagent as a versatile cyclodehydration agent

A simple and efficient synthetic method for the one-pot synthesis of 1,3,4-thiadiazoles utilizing Vilsmeier reagent was developed. In this method carboxylic acids and hydrazine were converted to 1,3,4-thiadiazoles in the presence of Vilsmeier reagent and Lawesson's reagent. The influence of the thionation reagent, solvent, temperature and time, in this reaction was discussed. The developed methodology for 1,3,4-thiadiazole synthesis has the advantage of simplicity, ambient reaction conditions, easy purification and good to excellent yield of products.

17O NMR studies of substituted 1,3,4-oxadiazoles

Three series of substituted 1,3,4-oxadiazoles were studied by 17O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values.

Near-infrared-absorbing organic electrochromic materials

The invention provides generally a new type of organic electrochromic Near Infrared (NIR)-active materials capable of absorbing and attenuating the light in the NIR region around 1550 nm and forming thin films on electrodes for variable optical attenuator

Synthesis, anti-HIV, and antifungal activity of new benzensulfonamides bearing the 2,5-disubstituted-1,3,4-oxadiazole moiety

A series of novel chiral and achiral N-[1-(1,3,4-oxadiazol-2ylthio)alkyl]- 4-methyl/chloro/methoxybenzenesulfonamides 5a-l were prepared by the reaction of 4-(4-methyl, chloro, methoxyphenylsulfonamido)alkyl carboxylic acid hydrazides 4a-l with CS2 and KO

An expeditious and convenient one pot synthesis of 2,5-disubstituted-1,3,4-oxadiazoles

A convenient, one pot procedure is reported for the synthesis of a variety of 2,5-disubstituted-1,3,4-oxadiazoles by condensing monoarylhydrazides with acid chlorides in HMPA solvent under the microwave heating. The yields are good to excellent, the process is rapid and does not need any added acid catalyst or dehydrating reagent.
