Analogous to Lawesson's reagent, it is used mainly as a selenation reagent. It is named after Professor John Derek Woollins, who is currently head of chemistry at the University of St Andrews.〔http://chemistry/staff/jdw/group/home.html〕 == Preparation == Woollins' reagent is commercially available. It can also be conveniently prepared in the laboratory by heating a mixture of dichlorophenylphosphine and sodium selenide (Na2Se), (itself prepared from reacting elementary selenium with sodium in liquid ammonia). An alternative synthesis is the reaction of the pentamer (PPh)5 with elemental selenium. 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「Woollins' reagent」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.
