2-[2-(3-Chlorophenyl)allyl]-2-ethylindan-1,3-dione is a key intermediate of indanofan, a novel herbicide. 2-[2-(3-Chlorophenyl)allyl]-2-ethylindan-1,3-dione was efficiently prepared by palladium-catalyzed coupling of 2-(3-chlorophenyl)prop-2-en-1-ol with 2-ethylindan-1,3-dione or palladium-catalyzed three-component coupling of allene, 3-bromochlorobenzene and 2-ethylindan-1,3-dione.
2-[2-(3-氯苯基)烯丙基]-2-乙基茚满-1,3-二酮是新型除草剂茚满丹的关键中间体。2-[2-(3-氯苯基)烯丙基]-2-乙基茚-1,3-二酮是通过钯催化 2-(3-氯苯基)丙-2-烯-1-醇与 2-乙基茚-1,3-二酮偶联或钯催化烯烃、3-溴氯苯和 2-乙基茚-1,3-二酮三组分偶联而有效制备的。
