The synthesis and reactivity of the tert-butyl-substituted arsanylborane tBuAsHBH 2 ⋅ NMe 3 (1) stabilized by a Lewis base (LB) are reported. Compound 1 is obtained by the reaction of in situ generated NatBuAsH with IBH 2 ⋅ NMe 3. By the reaction of 1 with Lewis acids the neutral compounds BBr 3 ⋅ tBuAsHBH 2 ⋅ NMe 3 (2) and BH 3 ⋅ tBuAsHBH 2 ⋅ NMe 3 (3) as well as coordination products towards Group 6 metal complexes [M(CO) 4(tBuAsHBH 2 ⋅ NMe 3) 2] (M=Cr, Mo, W; 4 a–c) are obtained. Upon reaction with IBH 2 ⋅ LB (LB=SMe 2, NMe 3), the cationic oligomeric arsanylboranes [(Me 3N ⋅ BH 2tBuAsHBH 2 ⋅ NMe 3)]I (5) and [H 2B(tBuAsHBH 2 ⋅ NMe 3) 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.
