Oxidative addition of cyanogen bromide to C,N-chelated and Lappert's stannylenes
Original language description
Stannylenes of L2Sn type bearing either C,N-chelating (1, L = L-CN = 2-(N,N-dimethylaminomethyl)phenyl) or bulky amido (2, L = L-N = N(SiMe3)(2)) ligands react with cyanogen bromide (Br-C N) via an oxidative-addition reaction to give monomeric six-coordinate (L-CN)(2)Sn(Br)CN (1a) and four-coordinate (L-N)(2)Sn(Br) CN (2a) stannanes in moderate yields. In solution, both 1a and 2a undergo instantaneous bromido-cyanido ligand redistribution reactions, leading to mixtures containing 1a, (L-CN)(2)SnBr2 (1b) and (L-CN)(2)Sn(CN)(2) (1c) or 2a, (L-N)(2)SnBr2 (2b) and (L-N)(2)Sn(CN)(2) (2c), respectively. The prepared species were characterised by multinuclear NMR spectroscopy in solution (1a-c and 2a-c) and in the solid state (1a-c). The crystal structures of 1a/b/c, 2a/b/c and sole 2b were determined by XRD analyses. DFT calculations and QTAIM analysis were also carried out to corroborate the experimental results.
