Reaction of the secondary alkynyl(Mes*)PH phosphane 2 with (Fmes)BH ⋅SMe gives the geminal PH/BH frustrated Lewis pair (FLP) 3. The PH and the BH functions are jointly used in the reduction of carbon monoxide under mild reaction conditions to give the [P]-CH -O-[B] product. A subsequent cycloaddition sequence results in the liberation of formaldehyde. The FLP 3 reacts with benzonitrile to give a P-benzamidine, and it couples two isonitriles at the FLP framework.
仲炔基（Mes*）PH膦2与（Fmes）BH·SMe反应生成偕二PH/BH受阻路易斯酸碱对（FLP）3。在温和的反应条件下，PH和BH官能团共同用于一氧化碳的还原反应，生成[P]-CH -O-[B]产物。随后的环加成反应序列导致甲醛的释放。FLP 3与苯甲腈反应生成P-苯甲脒，并且它在FLP框架上使两个异腈发生偶联反应。
