A one-pot procedure to synthesise aryldifluoroboranes, ArBF2, from bench-stable arylsilanes is presented. These ArBF2 react conveniently with aryllithium reagents to form unsymmetrical ArAr′BF and BArAr′Ar′′ in high yield. Examples of all three classes of borane have been characterised crystallographically, allowing for elucidation of geometric and crystal packing trends in crystalline ArBF2.

Four binuclear bis(α-dioximato)nickel(II) complexes (where the dioxime is 4,5-octanedione dioxime) were prepared by treatment of a monomeric bis(α-dioximato)nickel(II) species with the linking reagents (F2BRBF2, R = 1,4 -C6H4 or -(CH2)4−. The binuclear complexes consist of one FBRBF moiety linking the two bis(α-dioximato)nickel(II) units together by attachment of each boron to two oxygen atoms
通过用连接试剂(F 2)处理单体双(α-二氧肟基)镍(II)物种,制备了四种双核双(α-二氧肟基)镍(II)配合物(其中二肟为4,5-辛烷二酮二肟)。BRBF 2,R = 1,4- -C 6 ħ 4或- (CH 2)4 - 。双核配合物由连接两个双一个FBRBF部分(α-二肟)镍(II)单元,通过将每个硼与两个双(α-二氧肟基)镍(II)单元的两个氧原子连接在一起。几种单核双(α-二氧肟基)镍(II)配合物(其中二肟是包含两个RBF单元(R = C 6 H 5,nC的3,4-己二酮二肟或4,5-辛二酮二肟)还准备了4个H 9),一个RBF单元(R = C 6 H 5)和一个BF 2单元,或两个桥接二肟中的两个氧的BF 2单元。包含两个RBF单元的配合物以两种异构体形式存在,可以使用吸附色谱法进行分离。单核和双核复合物的特征在于其NMR(1 H,13 C和19 F)和IR光谱。含
