Herein, a new congruently melting mixed-anion compound Cs4B4O3F10 has been characterized as the first fluorooxoborate with [BF4] involving heteroanionic units. Compound Cs4B4O3F10 possesses two highlyfluorinated anionic clusters and therefore its formula can be expressed as Cs3(B3O3F6) ⋅ Cs(BF4). The influence of [BF4] units on micro-symmetry and structural evolution was discussed based on the parent
在此,一种新的同熔混合阴离子化合物 Cs 4 B 4 O 3 F 10已被表征为第一个具有 [BF 4 ] 的含杂阴离子单元的氟代硼酸盐。化合物Cs 4 B 4 O 3 F 10具有两个高度氟化的阴离子簇,因此其分子式可以表示为Cs 3 (B 3 O 3 F 6 ) ⋅ Cs(BF 4 )。基于母体化合物讨论了[BF 4 ]单元对微对称性和结构演化的影响。更重要的是,Cs 4B 4 O 3 F 10在所有可用的硼酸盐中显示出最低的熔点,从而为此类系统创造了新的记录。这项工作对于使用全氟化 [BF 4 ] 单元丰富和定制硼酸盐的结构具有重要意义。
Herein we reported the electrochemical hydroboration of alkynes by using B2Pin2 as the boron source. This unprecedented reaction manifold was applied to a broad range of alkynes, giving the hydroboration products in good to excellent yields without the need of a metal catalyst or a hydride source. This transformation relied on the possible electrochemical oxidation of an in situ formed borate. This
在此,我们报道了使用 B 2 Pin 2作为硼源的炔烃的电化学硼氢化反应。这种前所未有的反应歧管适用于广泛的炔烃,无需金属催化剂或氢化物源,即可使硼氢化产物具有良好的收率。这种转变依赖于原位形成的硼酸盐可能的电化学氧化。这种在未分开的电池中进行的阳极氧化允许形成推定的硼基自由基,该自由基与炔烃发生反应。
