A process for producing a polycarbonate resin by reacting raw materials of a bifunctional compound and diphenyl carbonate, where the bifunctional compound is an isomer mixture of: a 2,6-derivative of a bifunctional compound of formula (3-a): ##STR00001## and a 2,7-derivative of a bifunctional compound of formula (3-b): ##STR00002## where R.sub.2 in formulae (3-a) and (3-b) is, independently, H, CH.sub.3 or C.sub.2H.sub.5, and where the mixing ratio between the 2,6-derivative and the 2,7-derivative is 30:70 to 70:30.

An object of the present invention is to provide a novel substance that has a high reactivity as a fluorinating agent, is effectively used in various fluorination reactions, and is safely handled even in air. As the solution for achieving this object, the present invention provides a complex obtained by reacting bromine trifluoride with at least one metal halide selected from the group consisting of halogenated metals and halogenated hydrogen metals in a nonpolar solvent. This complex serves as a fluorinating agent that provides excellent fluorination performance and that is stable in air.

High heat monomer compounds, methods for preparing compounds, and compositions derived from the compounds are provided. Also provided are materials and articles derived from the compounds.
