Diborane is dimer of bh3
WebUnlike hydride ions, which are electron-rich nucleophiles, diborane is the dimer of an electron-deficient electrophilic species (BH 3). It is formed by reaction of a borohydride ion with strong acids and is used in 2.2′-dimethoxydiethyl ether (diglyme) as the solvent. Diborane reacts faster with carboxylic acids, reducing them to primary ...
