[tBu3PH][RBH(C6F5)2] (R=hexyl (8), Cy (9), norbornyl (10)) were prepared by reaction of the precursor frustrated Lewis pair (FLP) with H2. Subsequent reactions of 9 and 10 with CO2 afforded the species [((C6F5)2BR)2(μ‐HCO2)][tBu3PH] (R=Cy (11), norbornyl (12)). In related chemistry, combinations of the boranes RB(C6F5)2 (R=hexyl, Cy, norbornyl) with tBu3P treated with an equivalent of formic acid gave
B(C 6 F 4 H)3和i Pr 3 P或t Bu 3 P的溶液与CO 2的反应得到R 3 P(CO 2)B(C 6 F 4 H)3(R =i Pr(1),t Bu(2))。以类似方式,硼烷RB(C 6 F 5)2(R =己基,环己基(Cy),降冰片基),ClB(C 6 F 5)2或PhB(C将6 F 5)2与t Bu 3 P和CO 2合并,得到t Bu 3 P(CO 2)BR(C 6 F 5)2(R =己基(3),Cy(4),降冰片基(5),Cl(6),Ph(7))。同样,化合物[ t Bu 3 PH] [RBH(C 6 F 5)2 ](R =己基(8),Cy(9),降冰片基(10))是通过前驱物沮丧的路易斯对(FLP)与H 2反应制备的。的后续反应9和10与CO 2,得到物种[((C 6 ˚F 5)2 BR)2(μ-HCO 2)] [吨卜3 PH](R =成分Cy(11),降冰片基(12))
