Abstract
This invention relates to compounds having the formula ##STR1## in which R.sub.F is a perfluoro radical C.sub.n F.sub.2n+1 with n=1-20, and R is a C.sub.1-20 alkyl radical, a C.sub.4-15 cycloalkyl radical, a C.sub.5-20 cycloalkyl-alkyl radical, or a C.sub.6-20 aromatic radical. Said compounds constitute valuable intermediates for the synthesis of surface-active agents.
