Synthese und Struktur von 1,2-Bis(diisopropylamino)-1,2-diboretan / Synthesis and Structure of 1,2-Bis(diisopropylamino)-1,2-diboretane

Abstract

Substitution of two chlorine atoms in 1,2-bis(dichloroboryl)ethane with diisopropylamine yields 1,2-bis(chlorodiisopropylaminoboryl)ethane (4), which is reacted with Na/K alloy to give 1,2-bis(diisopropylamino)-1,2-diboretane (5) in 91% yield. 5 crystallizes in the space group P 21/c with the lattice constants a = 6.116(1), b = 16.658(5), c = 17.577(4) Å, β = 99.49(2)°.
