The H centres can also be replaced by alkyl and aryl. Structurally, these cations resemble guanidinium cations. The CN2S core is planar and the C-N bonds are short. Salts comprising these anions are typically prepared by alkylation of thiourea: :SC(NH2)2 + RX → ()+X− Hydrolysis of isothiouronium salts gives thiols. :()+X− + NaOH → RSH + OC(NH2)2 + NaX Chelating resins with isothiouronium groups are used to recover mercury and noble metals including platinum from solutions.〔(【引用サイトリンク】 Purolite S920 Isothiouronium Chelating Resin )〕 ==References== 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「isothiouronium」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
