Borohydride or hydroborate is also the term used for compounds containing [BH4−nXn]−, where n is an integer from 0 to 3, for example cyanoborohydride or cyanotrihydroborate [BH3(CN)]− …

但是并不完全如此，bh4-主要还是靠h过去亲核进攻，或者说是h伸过去挨着c,然后被c抓走，解离一个bh3。 而BH3却是B-H键协同和C=C配和，经历四元环状过度态完成对碳碳双键的加成。

2024年10月21日 · BH 4– (borohydride) has one boron atom and four hydrogen atoms. In BH 4– Lewis structure, there are four single bonds around the boron atom, with four hydrogen atoms …

2021年11月15日 · Tetrahydroborate ion (BH₄⁻): In this ion, the bonds between boron and hydrogen have a slight polarity; however, the overall geometry is symmetrical, which results in …

Beryllium borohydride is an inorganic compound with the chemical formula Be [B H 4]2. [2] Beryllium borohydride is formed by the reaction of beryllium hydride with diborane in an ether …

The bond between B and H in BH4- is considered polar covalent. In this molecule, boron (B) is more electronegative than hydrogen (H), causing a partial negative charge on the hydrogen …
