Notes:
The title compound was synthesized by hydrogenolysis of its precursor 2,2-bis(4-trifluoromethanesulfonatophenyl)hexafluoropropane (2) in the presence of a base. 2,2-Diphenylhexafluoropropane (6) can be appropriately functionalized at the 3,3′-positions to give the diamino (7), dibromo (11), dicarboxaldehydo (13), 3-ethynyl-3′-carboxaldehydo (14) derivatives which are important monomers in the synthesis of various high-temperatures resistant polymers and oligomers containing the hexafluoroisopropylidene (6F) group. 2,2-Bis(4-triflatophenyl)hexafluoropropane (2) undergoes quantitative dinitration at the 3,3′-positions to yield 2,2-bis(3-nitro-4-triflatophenyl)hexafluoropropane (3) which ultimately leads to the 3,3′-diamino-4,4′-bis(arylamino) (5) and 3,3′-diamino-4,4′-dihydroxy (8) derivatives which are specifically designed for phenylbenzimidazole, benzimidazoquinazoline, and benzoxazole polymers and oligomers.
