Polyfluorinated sulfonamides

摘要

This invention pertains to polyfluorinated sulfonamides having the formula CnF2n+1-CH2-bSO2-NRR' wherein n is a number of from 1 to about 20; b is an integer of from 2 to about 20; R is selected from the group consisting of a hydrogen radical and an alkyl radical having from 1 to about 10 carbon atoms; and R' is selected from the group consisting of a hydrogen radical, an alkyl radical of from 1 to about 10 carbon atoms, a cyclic alkyl radical of from 5 to 12 carbon atoms, and an aryl radical of from about 6 to 12 carbon atoms. These compounds are prepared through the action of polyfluorinated sulfonic chloride on an amino derivative.
