| titleOfInvention | Fluorinated alkylthiocyanate process |
| abstract | A process for the preparation of a thiocyanate of the Formula (II): Rf-Am-(CH2)n-SCN wherein Rf is a C2-C20 perfluoroalkyl radical, or a C5-C38 perfluoroalkyl radical having at least one ether oxygen atom; n is 1 to 3; m is 0 or 1; A is O, S, CO2, N(R1)R2, CON(R1)R2, SO2N(R1)R2 or (OCH2CHR3)aO; wherein a is 3 to about 15; R1 is H or alkyl radical of 1 to about 4 carbon atoms; R2 is C1-C12alkylene; and R3 is H or CH2Cl; said process comprising reacting a fluorinated iodide of the Formula (I): Rf-Am-(CH2)n-I wherein Rf, A, m and n are as defined above, with a thiocyanate salt M+(SCN)- wherein M is sodium or potassium, in the presence of a catalyst comprising a quaternary ammonium salt of the Formula (R¿4?)3(R5)N?+Y-¿ wherein R¿4? is butyl; R5 is methyl or butyl; and Y is Cl, Br, I, or HSO4; to yield the fluorinated thiocyanate of Formula (II) as defined above is disclosed. |
