Palladium-catalyzed activation of carbon–sulfur bonds allows aryne insertion into aryl thiocyanates to generate new C–SAr and C–CN bonds in one step. The readily available starting materials make this method efficient in generating a variety of 1,2-thiobenzonitriles. By choosing an oxygen atmosphere the yields are increased and side reactions are minimized.
钯催化的碳硫键活化可以使芳烃插入芳基硫氰酸酯中,从而一步生成新的C-SAr和C-CN键。容易获得的起始原料使该方法有效地产生各种1,2-硫代苄腈。通过选择氧气气氛,可以提高收率并最大程度地减少副反应。
