1,3‐Addition of Azides to Azadecaborane: 6‐Azadecaborane‐4,9‐diyltriazenes nido ‐NB 9 H 12 ( 1 ) reacts with azides RN 3 to form a coordinative B–N bond between B9 and N1 of RN 3 , accompanied by the α‐addition of the B4–H bond of 1 to the N3 atom of RN 3 . The products 2a, b (R = H, CH 2 Ph, respectively) thus contain an azadecaborane skeleton and a five‐membered unsaturated B 2 N 3 ring with a common B–B edge. The product 2a crystallizes in the space group Pna 2 1 .
