General description

Benzenesulfonic acid, also known as besylic acid, is a strong organic acid commonly used as an acid catalyst in various organic reactions, such as esterification, alkylation, and condensation reactions. It is also used as a sulfonating agent to introduce sulfonic acid (SO3H) groups into organic compounds, which can be useful in the synthesis of several dye intermediates.

A series of TiO(2)-Cu(2)O mixed oxides were prepared by the hydrolysis of titanium butoxide and reduction of copper acetate with hydrazine. These composite oxides were characterized by X-ray diffraction (XRD), inductively coupled plasma spectrometry (ICP), high-resolution transmission electron microscopy (HRTEM)

Pseudomonas aeruginosa RW41 is the first bacterial strain, which could be isolated by virtue of its capability to mineralize 4-chlorobenzenesulfonic acid (4CBSA), the major polar by-product of the chemical synthesis of 1,1,1-trichloro-2,2-bis-(4-chlorophenyl)ethane (DDT). This capability makes the isolate a promising

A novel, convenient, and efficient method has been developed for selective synthesis of spirocycle, polycycle, and di- and tetrahydronaphthalene systems from aryl-substituted propargylic alcohols by FeCl3- or TsOH-catalyzed multiple activations of unsaturated C-C bonds and C-H bonds.
