A compound having the formula
CF.sub.3--CH(OH)--CH.sub.2--(L).sub.n--CH.sub.2--SH or a disulfide
thereof. Each L is substituted or unsubstituted methylene, substituted or
unsubstituted oxyalkylene, and alkyl-substituted or unsubstituted
siloxanylene. The compound is free of carboxysilane linkages. The value
of n is a positive integer. A metal surface having the group
CF.sub.3--CH(OH)--CH.sub.2--(L).sub.n--CH.sub.2--S-- bound thereto. A
method of making CF.sub.3--CH(OH)--CH.sub.2--(L).sub.n--CH.sub.2--SH by:
reacting OHC--CH.sub.2--(L).sub.n--CH.sub.2--X with
(trifluoromethyl)trialkylsilane to form
CF.sub.3--CH(OH)--CH.sub.2--(L).sub.n--CH.sub.2--X; reacting the
intermediate with a thiocarbonyl compound to form an adduct; and
hydrolyzing the adduct followed by protonation. X is a halogen.
