Abstract Reactions of trifluoromethane- and tridecafluorohexanesulfonyl chlorides with silyl enol ethers have been investigated in the presence of a ruthenium(II) phosphine complex. Perfluoroalkylation and chlorination occurred depending on the substituent of silyl enol ether; i.e. perfluoroalkylated compound was selectively obtained in the reactions with silyl enol ether possessing an electron-withdrawing

Preparation of perfluoroalkane carboxylic and sulphonic acid derivatives by the action of metallic couples on perfluoroalkyl iodides in dimethyl sulphoxide
Perfluoroalkyliodides react with carbon dioxide and sulphur dioxide, in the presence of zinc–copper type metalliccouples in dimethylsulphoxide, to give the corresponding carboxylic and sulphonicacidsderivatives in 40–80% yields.

[Problem] to provide an aromatic imide compound wherein the sensitivity for visible light such as g-line, h-line etc. is increased and solubility is also improved.
[Means for solving problem] The aromatic imide compound of the invention is a compound represented by the formula (1) below (in the formula, R
1
represents a haloalkyl group having 1 to 7 carbon atoms or a haloaryl group, R
2
represents a group containing a substituted or unsubstituted, aliphatic or aromatic group which may have a heteroatom, and adjacent R
2
s may form an imido group by connecting each other, R
3
represent a halogen atom or a hydrocarbon group, m is zero or an integer of 1 or more, n is zero or an integer of 1 or more, and a sum of n and m is 1 to 6). These compounds are obtained by following processes. A halogenated naphtharic anhydride is reacted with an aromatic group-containing hydrocarbon such as ethynylbenzene to prepare a naphthalic anhydride substituted by an aromatic group-containing group. The obtained compound is then reacted with hydroxylamine hydrochloride to be made N-hydoxyimidization. Finally, the resultant compound is reacted with a sulfonyl halide such as trifluoromethylsulfonyl chloride to obtain the objective compound.
