ABSTRACT:
Tris-perfluoroalkyl terminated neopentyl alcohols of the formula (R.sub.f --E.sub.n --X--CH.sub.2).sub.3 CCH.sub.2 OH prepared from halogenated neopentyl alcohols and thiols of the formula R.sub.f --E.sub.n --SH, amines of the formula R.sub.f --E.sub.n --NH--R, alcohols of the formula R.sub.f --E.sub.n --OH, perfluoro-acids or amides, are described. The alcohols react with isocyanates to prepare urethanes; with acids or derivatives, to prepare esters or carbonates; with epoxides to form ethers. Further, they may be converted to halide intermediates. The products all contain the residue of at least one R.sub.f -neopentyl alcohol containing three perfluoroalkyl hetero groups.
