Claim:
A sulfonyl halide compound shown by the following formula (I-b), wherein R 1 represents —R 5 , —COR 6 , —COOR 6 , —CON(R 6 )(R 7 ), —N(R 6 )(R 7 ), —N(R 6 )CO(R 7 ), —N(R 6 )COOR 7 , —N(COR 6 )(COR 7 ), —SR 6 , —SOR 6 , —SO 2 R 6 , or —SO 2 (OR 6 ), (wherein R 5 represents a substituted or unsubstituted, linear, branched, or cyclic monovalent hydrocarbon group having 1-30 carbon atoms, a substituted or unsubstituted aryl group having 6-30 carbon atoms, or a substituted or unsubstituted, monovalent hetero cyclic organic group having 4-30 carbon atoms, R 6 and R 7 individually represent a hydrogen atom, a substituted or unsubstituted, linear, branched, or cyclic monovalent hydrocarbon group having 1-30 carbon atoms, a substituted or unsubstituted aryl group having 6-30 carbon atoms, or substituted or unsubstituted, monovalent hetero cyclic organic group having 4-30 carbon atoms, provided that when both R 6 and R 7 are present in the group R 1 , R 6 and R 7 may bond to form a ring), two or more R 1 groups, if present, may be either the same or different, the R 1 group may bond to form a ring with carbon atoms in the norbornene structure, and two or more R 1 groups may bond to form a ring; R 2 , R 3 , and R 4 individually represent a hydrogen atom or a linear, branched, or cyclic alkyl group having 1-30 carbon atoms; k is an integer of 0 or more; n is an integer of 0-5; and X is a halogen atom.
