Synthesis of 6-aza-nido-decaborane(12) and its derivatives
Abstract
The aza-nido-borane 6-NB9H12(1) has been prepared by treatment of the reaction intermediate formed in the reaction of B10H14 and NaNO2 in tetrahydrofuran with concentrated H2SO4; hydrolysis of compound (1) afforded arachno-4-NB8H13(2) and the addition of Lewis bases produced the arachno-9-L-6-NB9H12(3) compounds [L = Me2S (3a), MeCN (3b), and PPh3(3c)].
