General Description

Alpha, alpha, alpha', alpha'-tetrabromo-p-xylene is a chemical compound consisting of four bromine atoms attached to a xylene molecule. It is commonly used as a flame retardant and is included in a variety of products, including plastics, textiles, and electronics. ALPHA,ALPHA,ALPHA',ALPHA'-TETRABROMO-P-XYLENE is known for its high thermal stability and effectiveness in preventing the spread of fires. However, it has been found to be persistent in the environment and has been linked to potential health concerns, including reproductive and developmental toxicity. As a result, there has been increasing scrutiny and regulation of alpha, alpha, alpha', alpha'-tetrabromo-p-xylene in recent years.

Experimental and Theoretical Study of the Reaction Kinetics of 2,5-Dimethylterephthalonitrile Bromination Compared to 1,4-Dimethylbenzene Bromination

Experimental and theoretical studies showed the differences observed in the benzylic tetrabromination reactions in 2,5-dimethylterephthalonitrile compared to 1,4-dimethylbenzene. It was observed that the compound containing the nitrile substituent underwent a slower bromination reaction, with the formation of four intermediate compounds, while for the compound without substituents, the reaction was faster and only two intermediate compounds were observed.

SYNTHESIS OF 1,1,2,2,9,9,10,10-OCTAFLUORO-PARA-CYCLOPHANE

1,1,2,2,9,9,10,10-Octafluoro-para-cyclophane was obtained by the pyrolysis of α,α'-di-bromo-α,α,α',α'-tetrafluoro-p-xylene using argon as the diluent with further trapping of the pyrolysis products in boiling toluene.The pyrolysis zone was filled with a copper packing to bind bromine.An efficient scheme was also developed for the preparation of α,α'-dibromo-α,α,α',α'-tetrafluoro-p-xylene starting from p-xylene.
