摘要:
[MEANS FOR SOLVING PROBLEMS] A novel cyclic carboxylic acid formed by the addition reaction of an unsaturated carboxylic acid with a conjugated diene compound; a metal salt of the acid; a compounding agent (A) for antifouling coating compositions which comprises at least one of the novel cyclic carboxylic acid, derivatives of the cyclic carboxylic acid (excluding the metal salts), metal salts of the cyclic carboxylic acid, and metal salts of the cyclic carboxylic acid derivatives; and an antifouling coating composition comprising the compounding agent (A) and a copolymer (B) for self-polishing type antifouling coating compositions. [EFFECTS] The composition can form an antifouling coating film which is reduced in environmental burden, evenly wears at a given rate over long, and can retain excellent antifouling performance over long. It is applicable also to ships and other objects for use in highly fouling waters.

摘要:
The invention is directed to the cross-metathesis and ring-closing metathesis reactions between geminal disubstituted olefins and terminal olefins, wherein the reaction employs a Ruthenium or Osmium metal carbene complex. Specifically, the invention relates to the synthesis of α-functionalized or unfunctionalized olefins via intermolecular cross-metathesis and intramolecular ring-closing metathesis using a ruthenium alkylidene complex. The catalysts preferably used in the invention are of general formula (I) or (II), wherein: M is ruthenium or osmium; X and X1 are each independently an anionic ligand; L is a neutral electron donor ligand; and, R, R?1, R6, R7, R8, and R9¿ are each independently hydrogen or a substituent selected from the group consisting of C¿1?-C20 alkyl, C2-C20 alkenyl, C2-C20 alkynyl, aryl, C1-C20 carboxylate, C1-C20 alkoxy, C2-C20 alkenyloxy, C2-C20 alkynyloxy, aryloxy, C2-C20 alkoxycarbonyl, C1-C20 alkylthio, C1-C20 alkylsulfonyl and C1-C20 alkylsulfinyl.
