The synthesis and reactivity of the tert-butyl-substituted arsanylborane tBuAsHBH(2) . NMe3 (1) stabilized by a Lewis base (LB) are reported. Compound 1 is obtained by the reaction of in situ generated NatBuAsH with IBH2 . NMe3. By the reaction of 1 with Lewis acids the neutral compounds BBr3 . tBuAsHBH(2) . NMe3 (2) and BH3 . tBuAsHBH(2) . NMe3 (3) as well as coordination products towards Group 6 metal complexes [M(CO)(4)(tBuAsHBH(2) . NMe3)(2)] (M=Cr, Mo, W; 4 a-c) are obtained. Upon reaction with IBH2 . LB (LB=SMe2, NMe3), the cationic oligomeric arsanylboranes [(Me3N . BH(2)tBuAsHBH(2) . NMe3)]I (5) and [H2B(tBuAsHBH(2) . NMe3)(2)]I (6) were isolated. Compound 1 was also used as starting material for the synthesis of the first oligomeric arsanylboranes obtained by thermal oligomerization under different conditions. DFT computations support the experimental observations.
