title: Twice silicon-induced C-H activation and tautomerisation of a beta-diketiminato ligand and formation of new types of N-heterocyclic silanes.
abstract: Unexpected formation of the novel dianionic N,C-chelate ligand LD2- [HC[C(Me)-NR][C(NHR)=CH]]2- occurs by a twice silicon-assisted C-H bond activation of a terminal methyl group on a beta-diketiminato ligand backbone, starting from the corresponding lithium beta-diketiminide and silicon tetrabromide to give the new N-heterocyclic dibromosilanes and .
