✦ Synopsis

Iminoboranes tBuB = NR (R = tBu, Mes: 1 a, b) undergo mi-ml/n). The cyclic diaminostannylene [ -Sn -N(tBu)nostannation by the diaminostannylene Sn[N(SiMe,)& (2 b) to %Mez -N(tBu) -1 (3 b), instead, simply adds the boranes 1 a, b give (Me3Si)2N -B(tBu) = NR -Sn-N(SiMe3)2 (4a. b).

The stanacross one of its Sn-N bonds to form the bicyclo[2.2.0]hexenenylene 4b remains monomeric in the crystal (space group type products 5a,b.
