The invention describes syntheses and purifications of several perfluorocarbon-soluble compounds having a general formula RF - L - X or RF - L - X - L - RF, wherein RF is a perfluorocarbon group, X is a hydrophilic moiety, and L is an amide linkage of general structure -CO-NH-. The invention also provides microemulsions comprising a PFC forming an oil phase, water or aqueous solution forming a water phase, and a PEG-based fluorosurfactant with an HFB (hydrophilic groups to fluorophilic groups balance) value from about 7 to about 13. The invention also provides a method of amidification of a fluorocompound. The method involves mixing perfluoracid chloride of a general formula CnF2n+1COCI with a compound containing an amine group with a general structure R-NH2 under reaction conditions sufficient to obtain a product having a general formula CnF2n+1-CONH-R.
