A fluorine anion-mediated diphosphination of ortho-quinone methide precursors (2-(chloromethyl)silyloxybenzenes) with diphosphines has been developed. The reaction proceeds smoothly under mild conditions (CH2Cl2 solvent, 0 °C) to form the corresponding 2-(phosphinomethyl)oxyphosphinobenzenes, which are potential bidentate ligands in metal catalysis. Additionally, some mechanistic investigations are
的氟阴离子介导diphosphination邻-quinone甲基化物的前体(2-(氯甲基)silyloxybenzenes)与二膦已经研制成功。反应在温和条件下(CH 2 Cl 2溶剂,0°C)平稳进行,形成相应的2-(膦甲基)氧膦基苯,它们是金属催化中潜在的二齿配体。此外,还进行了一些机械研究。
