Synthesis of perfluoro[2.2]paracyclophane

(Chemical Equation Presented) A synthesis of perfluoro[2.2]paracyclophane has been sought ever since the partially fluorinated octafluoro[2.2]- paracyclophane (AF4) was prepared and its chemistry studied. This compound has now been prepared in 39% yield from the precursor, 1,4-bis(chlorodifluoromethyl) -2,3,5,6-tetrafluorobenzene by its reaction with Zn when heated in acetonitrile at 100°C. Two preparations of the precursor, first from 1,4-dicyano-2,3,5,6- tetrachlorobenzene and an improved method beginning from 1,2,4,5- tetrachlorobenzene, are also described as are key comparisons to our related synthesis of AF4.

Synthesis of tetrachloroisophthalic and -terephthalic aldehydes and stable bis(nitrile oxides) based on them

A new route for the synthesis of 2,4,5,6-tetrachloroisophthalic and 2,3,5,6-tetrachloro-terephthalic aldehydes from the corresponding tetrachlorobenzenes was developed. The method involves dichloromethylation of the initial compounds with chloroform in th
