A new benzyne transformation is described that affords versatile biaryl structures without recourse to transition-metal catalysis or stoichiometric amounts of organometallic building blocks. Aryl sulfonamides add to benzyne upon fluoride activation, and then undergo an aryl Truce-Smiles rearrangement to afford biaryls with sulfur dioxide extrusion. The reaction proceeds under simple reaction conditions
描述了新的苯并炔转化,其提供通用的联芳基结构,而无需求助于过渡金属催化或化学计量的有机金属结构单元。芳基磺酰胺在氟化物活化后加至苯并,然后进行芳基Truce-Smiles重排,得到具有二氧化硫挤出的联芳基。该反应在简单的反应条件下进行,并且具有空间位阻阻转异构二芳基胺的合成的优异范围。
