Patent ID: 7186773

Claim:
A process for preparing a fluorine-containing norbornene derivative having a fluorine-containing tertiary alcohol structure which is represented by the formula (4): wherein Z 1 is the same or different and each is: R 1 ) n2 -Z 2 in which Z 2 is: wherein Rf 1 is a fluorine-containing alkyl group having 1 to 10 carbon atoms or a fluorine-containing alkyl group which has 1 to 10 carbon atoms and ether bond, Rf 2 is a fluorine-containing alkyl group having 1 to 10 carbon atoms or a fluorine-containing alkyl group which has 1 to 10 carbon atoms and ether bond, R 3 is H or a hydrocarbon group having 1 to 10 carbon atoms, R 1 is a divalent organic group, n2 is 0 or 1; Y is the same or different and each is H, F, Cl, an alkyl group having 1 to 10 carbon atoms or a fluorine-containing alkyl group which has 1 to 10 carbon atoms and may have ether bond; R is the same or different and each is H or an alkyl group having 1 to 10 carbon atoms; n is 0 or an integer of from 1 to 5; m is an integer of from 1 to 5; n1 is an integer of from 1 to 5; m+n1=6, said process being characterized by reacting a norbornene derivative represented by the formula (3): wherein X 3 is the same or different and each is: R 1 ) n2 —X 4 in which X 4 is —COOR 2 , wherein R 2 is an alkyl group having 1 to 5 carbon atoms, X 5 is halogen atom; R 3 , Rf 1 , R 1 , Y, R, m, n, n1 and n2 are as defined above, with a fluoroalkylation agent which introduces Rf 2 to X 4 .
