The preparation of organohaloboranes R3−nBXn (R = CH3, C2H5, C6H5; X = F, Cl, Br. I) by two convenient procedures is described. These are based on the action of boron halides on tetraorganostannanes and dialkylamino-organoboranes respectively.
描述了通过两种方便的方法制备有机卤代呋喃酮R 3- n BX n(R = CH 3,C 2 H 5,C 6 H 5; X = F,Cl,Br。I)。这些是基于卤化硼分别对四有机锡烷和二烷基氨基-有机硼烷的作用。

Ferrocene, cymantrene and methylcymantrene react with BI3, BBr3, C6H5BI2 and CH3BI2 in boiling CS2 or C6H12 forming air-sensitive metallocenylhaloboranes. The direct dichloroborylation is only possible with ferrocene. Starting from metallocenyliodoboranes the corresponding substituted metallocenylboranes are obtained by halogen exchange with AsF3 or AsCl3, by methylation with Sn(CH3)4, by ether cleavage
二茂铁,环丙三烯和甲基环丙三烯在沸腾的CS 2或C 6 H 12中与BI 3,BBr 3,C 6 H 5 BI 2和CH 3 BI 2反应,形成对空气敏感的茂金属卤代硼烷。仅二茂铁才可能直接进行二氯硼酸化。由金属茂基碘硼烷开始,通过与AsF 3或AsCl 3进行卤素交换,与Sn(CH 3)4甲基化,通过醚裂解(C 2 H 5)2来获得相应的取代的金属茂基硼烷。O,通过与(CH 3 S)2的氧化还原反应并通过与R 2 NH的反应而形成。1 H和13 C NMR光谱表明,与半环大麦环戊烷相比,在二茂铁环戊烷中3,4-质子比2,5-质子更脱保护。具有α-茂金属碳原子离子的等电子金属茂硼烷比苯基硼烷弱路易斯酸。它们分别与吡啶和二甲基亚砜形成供体-受体化合物。

The photolysis of aryl iodides in the presence of boron halides results in the formation of arylboron dihalides and diarylboron halides by free-radical substitution reactions. Hydrolysis of the products gives the corresponding boronic and borinic acids. Alkyl iodides and di-iodo-compounds behave in a similar manner. The photolysis and subsequent hydrolysis of mixtures of bromo- or chloro-benzene with
The heteroaryl borates Li[C4Me4NBH3] (6) and Na[C3H3N2(BMe3)2]• 2 C4H8O (8) are obtained by treatment of Li[C4Me4N] and Na[C3H3N2] with Me2S • BH3 and BMe3, respectively. The X-ray structure of [Na(C4H8O)6][C3H3N2(BMe3)2] (10) is reported.

In the reaction of cis-(CO)4(SnPh3)Re[C(OEt)NR2] (R ipr (isopropyl), chex (cyclohexyl)) with BI3 the Lewis acid attacks the triphenylstannyl ligand. Substitution of a phenyl for a iodine group leads to equilibrium mixtures of rhenium carbene complexes of general formula cis-(CO)4(SnPh3−χIχ)Re[C(OEt)NR2] (χ = 1−3; R ipr, chex). By changing the solvent and ratio of can be shifted such that only one
