We describe a method for intramolecular desulfonylative coupling using bis(cyclooctadiene)nickel as a catalyst. A broad range of aromatic, heteroaromatic and aliphatic sulfones can be utilized as substrates in this process. This method provides an atom‐economical route to the synthesis of various biaryls and an efficient tool for the catalytic conversion of sulfonyl groups, representing a significant
我们描述了一种使用双(环辛二烯)镍作为催化剂的分子内脱磺酰基偶联的方法。在该方法中,可以使用各种各样的芳族,杂芳族和脂族砜作为底物。该方法为各种联芳基的合成提供了一种原子经济的途径,也是磺酰基催化转化的有效工具,代表了有机合成的重大进展
