Usage

General Description

2,4-DIBROMOBIPHENYL is a chemical compound consisting of two bromine atoms attached to a biphenyl molecule. It is classified as a polybrominated biphenyl and is used as a flame retardant in various industrial applications. The compound is also known to have toxic effects on the environment and human health, with potential for bioaccumulation and persistence in the environment. Due to its hazardous properties, 2,4-DIBROMOBIPHENYL has been the subject of regulatory restrictions and is being phased out of use in many countries. Efforts are being made to find safer alternatives to this chemical for flame retardant applications.

Process for the preparation of bromoarylacetylene and aryldiacetylene precursors

Bromoarylacetylenes such as m-bromophenylacetylene and certain precursors to such bromoarylacetylene are prepared by reacting an aryldibromide with a substituted terminal acetylene compound containing at least three carbon atoms and a hydroxy group on the carbon atom adjacent to the acetylene group in the presence of a dialkyl or trialkyl amine solvent and a catalyst system consisting of a palladium complex containing two halogen moieties and two tri-substituted phosphine moieties. Additional triphenylphosphine can be added. A cuprous iodide promoter is also employed in the reaction sequence. The bromoarylacetylenes can be reacted with a substituted terminal acetylene compound as defined using the same catalyst system as defined to produce the corresponding aryldihydroxy substituted acetylenes. Certain bromophenylhydroxy substituted acetylenes are claimed as new compositions.
