The thia‐Michael addition reaction has been demonstrated to be a highly powerful tool in
organic synthesis. Indeed, the influential nature of this reaction has been well‐established in …

The first thiocarboxylation of styrenes and acrylates with CO2 was realized by using visible
light as a driving force and catalytic iron salts as promoters. A variety of important β …

Brönsted acid catalysts have been used in a number of organic transformations. To
overcome limitations, such as toxicity, volatility, high price and hazardous nature of the …

The catalytic potential of various protic acids has been assessed for the one pot tandem
condensation–cyclisation reaction involving an aldehyde, an amine, and thioglycolic acid to …

The catalytic potential of different fluoroboric acid-derived catalyst systems viz. aq HBF4,
solid supported HBF4, metal tetrafluoroborates (inorganic salts), solid supported metal …

Perlite sulfonic acid (Perlite-SO 3 H (PeSA)) has been synthesized by grafting the sulfonic
groups on the perlite surface as naturally and cheap support to produce novel …

A convenient and clean procedure of esterification is reported by direct condensation of
equimolar amounts of carboxylic acids with alcohols catalyzed by an easy to prepare …

CBS-QB3 enthalpies of reaction have been computed for the conjugate additions of MeSH
to six α, β-unsaturated ketones. Compared with addition to methyl vinyl ketone, the reaction …

Carbon dioxide (CO2) utilization for the production of fuels and energy-rich chemicals is one
