Oxidation of 3- and 4-pentafluorosulfanyl-substituted anisoles and phenols with hydrogen peroxide and sulfuric acid provided a mixture of SF5-substituted muconolactone, maleic, and succinic acids. A plausible mechanism for the formation of the aliphatic SF5 compounds was presented and their chemical reactivity was investigated. SF5-substituted para-benzoquinone was synthesized; its oxidation le...

In this research, an efficient synthesis toward 2-(2-((4-Methoxybenzoyl)imino)-4-(4-methoxyphenyl)thiazol-3(2H)-yl)-2-phenylacetic acid via a three-component tandem reaction using aroylisothiocyanate, phenyl glycine, and 4-methoxyphenacyl bromide in an ionic liquid (IL) has been described. 1-Methyl-3-pentylimidazolium bromide (IL) has been employed as a recyclable green solvent. The work-up pro...

Methanesulfonic acid (MSA) was found to be an efficient catalyst for the synthesis of 1-substituted-1H-1,2,3,4-tetrazoles. A series of 1-substituted tetrazole compounds were synthesized from the reaction of various primary amines, sodium azide and triethyl orthoformate in the presence of catalytic amounts of MSA at room temperature. In this protocol, some of the tetrazole derivatives were synth...

A simple, efficient and environment-friendly procedure for the synthesis of 5-arylidene rhodanines derivatives via a Knoevenagel type reaction was developed using rhodanine, variety differently substituted aldehydes Na2SO3 as benign catalyst in ethanol. Selected were subjected to basic hydrolysis afford 2-mercapto-3-substituted-acrylic acids. The presence boronic acid group is well tolerated su...
