N,N-Dimethyl-1,3-propanediamine → 1-Hexanesulfonamide, N-[3-(dimethylamino)propyl]-1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluoro-

Participants

Reaction Steps

A mixture of dimethylaminopropylamine, H2NC3H6N(CH3)2 (12.2 g, 0.12 mole), triethylamine, (C2H5)3N (8.1 g, 0.08 mole) and toluene (60 g) was first prepared at ambient temperature and about atmospheric pressure in an inert atmosphere of nitrogen. To this mixture was added perfluorohexanesulfonyl fluoride, C6F13SO2F (41.0 g, 0.10 mole). The total mixture was then heated in a stainless steel reaction vessel at 90° C. for a period of about 3 hours forming a homogeneous reactant solution. During this period the aforementioned Reaction (a) takes place to produce intermediate N-[3-(N',N'-dimethylamino)propyl]perfluorohexane sulfonamide, C6F13SO2N(H)C3H6N(CH3)2.
