<p><P>PROBLEM TO BE SOLVED: To provide a method of efficiently removing dissolved palladium from a solution after an organometallic reaction using a palladium catalyst. <P>SOLUTION: The solution after the organometallic reaction using the palladium catalyst is brought into contact with an adsorbent comprising of an amide-containing cyclic sulfide compound represented by formula (1), or an adsorbent where the amide-containing cyclic sulfide compound represented by formula (1) is fixed on a carrier, wherein each R represents, independently, a hydrogen atom, a 1C-18C chain hydrocarbon group, a 3C-10C alicyclic hydrocarbon group or a 6C-14C aromatic hydrocarbon group; each n represents, independently, an integer of 1-4; each L represents, independently, a 1C-8C alkylene group or a 6C-14C arylene group. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
