Conclusion In summary, C–S bond formation reactions leading to different sulfide
derivatives can be achieved by two-component or three-component reaction. The major …

Surface functionalization of SBA-15 followed by its reaction with Cu (OAc) 2 has been
carried out to develop a new Cu-grafted functionalized mesoporous material, which …

We report herein an efficient synthesis of 4-substituted triazolyl-nucleosides and their in vitro
cytostatic activity. The synthesis is based on a straightforward 1, 3-dipolar cycloaddition …

Lewis acids are important and interesting catalysts in most organic transformations. Among
different Lewis acids, Zr (IV) species such as ZrCl 4 and ZrOCl 2· 8H 2 O are allocated …

Fluoroboric acid adsorbed on silica-gel (HBF4–SiO2) has been found to be a new and
highly efficient heterogeneous catalyst for thia-Michael addition to α, β-unsaturated carbonyl …

An efficient, mild and rapid procedure for the acylation and alkylation of aromatic and
aliphatic thiols mediated on a silica gel surface at room temperature is described. The …

Florisil (magnesium polysilicate) is an efficient and eco-friendly reagent for the deprotection
of tert-butyl carbamates, carbonates, and ethers. Moderate to excellent yields could be …

An effective and proficient process for the synthesis of a variety of thioethers via the one‐
step reaction of benzyl halides, aryl halides, and thiourea is presented. This strategy is a one …

A simple and efficient protocol has been introduced for the Michael addition of thiols to α,
βunsaturated carbonyl compounds under solvent-free conditions without the use of a …
