Tantalizing chemistry of the half-sandwich silylhydride complexes of niobium: identification of likely intermediates on the way to agostic complexes.
Reactions of the compound [NbCp(ArN)(PMe3)2] with chlorosilanes HSiRR'Cl give a series of silyl complexes [NbCp(ArN)(PMe3)(H)-(SiRR'Cl)] and [NbCp(ArN)(PMe3)(Cl)(SiRR'H)] which are likely intermediates to the agostic complexes [NbCp(ArN(RR'2Si-H...))-(PMe3)(Cl)].
