two‐step process to yield K[(C2F5)3BCOCOPh] and K[(C3F7)3BCOCOPh] as isolable intermediates. Crystal structures were obtained of K[(C2F5)3BCOCOPh], K[(C2F5)3BCOOH]⋅H2O, (C2F5)3BCO, K[(C3F7)3BCOOH] ⋅2 H2O, and (C3F7)3BCO. In the crystal structures of (C2F5)3BCO and (C3F7)3BCO the CO bond lengths are 1.109(2) and 1.103(5) Å, respectively, which are among the shortest observed to date. Tris(pentafluoroethyl)borane
(C 2 F 5)3 BCO和(C 3 F 7)3 BCO是新的三(全氟烷基)硼烷羰基,是通过新颖的合成路线,使用可商购的前体,通过使K [(C 2 F 5)反应来制备的在最后一步中,用浓硫酸加入3 BCOOH]和K [(C 3 F 7)3 BCOOH]。羧酸K [(C 2 F 5)3 BCOOH]和K [(C 3 F 7)3BCOOH],通过在Cs的[(C的CC三键的氧化裂解制备2 ˚F 5)3 BCCPh]和Cs [(C 3 ˚F 7)3 BCCPh]在两步骤过程中得到K [(C 2 ˚F 5)3 BCO COPH]和K [(C 3 ˚F 7)3 BCO COPH]作为可分离的中间体。K [(C的获得晶体结构2 ˚F 5)3 BCO COPH],K [(C 2 ˚F 5)3 BCOOH] ⋅ħ 2 O,(C 2 ˚F 5)3 BCO,K [(C 3 ˚F 7)3 BCOOH]
