Usage

General Description

DI-O-TOLYL CARBONATE, also known as 2,4-di-O-tolyl carbonate or DTC, is a chemical compound commonly used in the production of high-performance polymers and resins. It is a clear, colorless, and odorless liquid that is insoluble in water but soluble in organic solvents. DTC is often utilized as a crosslinking agent in the synthesis of polymers such as polyurethanes and polycarbonates, as well as in the production of specialty coatings and adhesives. It is also employed as a chemical intermediate in the manufacturing of pharmaceuticals, agrochemicals, and other organic compounds. DTC is considered to be a versatile and valuable chemical in various industrial applications due to its high reactivity and compatibility with a wide range of other compounds.

Transesterification of dimethyl carbonate with phenol using Br?nsted and Lewis acidic ionic liquids

Transesterification reaction of dimethyl carbonate with phenol to methylphenyl carbonate and diphenyl carbonate using dibutyltin oxide catalyst in conjunction with Br?nsted and Lewis acidic ionic liquids was studied. It was observed that the use of ionic liquids significantly enhances the yield of diphenyl carbonate. The ionic liquid having p-toluenesulfonate as anion and metal halide (e.g. ZnCl2) as Lewis acid precursor exhibited higher activity and selectivity for diphenyl carbonate formation. Furthermore, the Br?nsted and Lewis acidity of ionic liquids was measured by IR spectroscopy using pyridine as a probe and their Lewis acidity order was also determined.

Metal Template ortho-Acylation of Phenols. Direct Synthesis of Salicylic Acid Chlorides and Derivatives

A direct synthesis of salicylic acid chlorides is achieved via "metal-driven" intracomplex acylation of bromomagnesium and aluminum phenoxides with phosgene.Salicylic acids 5 and some derivatives 6, 7 can be obtained by quenching the reaction mixture with convenient reagents.Moreover the reaction of lithium phenylacetylide with 3 provides a new convenient approach to ortho-hydroxyaryl alkynyl ketones like 8.The oriented complex 2, involving the metal phenoxide and phosgene is proposed to account for the ortho-regioselective control of the reaction.
