Diboron tetrachloride is a chemical compound with the formula B2Cl4. It can be formed by the electrical discharge procedure of boron trichloride at low temperatures.

Contents

Synthesis

The electrical discharge procedure of boron trichloride can be divided into three steps:

BCl3 → BCl2 + Cl Cl + Hg(electrode) → HgCl or HgCl2 2BCl2 → B2Cl4

Reactions

The compound is used as a reagent for the synthesis of organoboron compounds. For instance, diboron tetrachloride reacts with ethylene:

CH2=CH2 + B2Cl4 → Cl2BCH2CH2BCl2

The compound absorbs hydrogen quickly at room temperature:

3 B2Cl4 + 6H2 → 2 B2H6 + 4 BCl3
