摘要：

Treatment of [RuCl2(PPh(3))(3)] With azine phosphines gives complexes showing strong agostic interactions between ruthenium and C-H bonds of tert-butyl, methyl, aryl or alkenyl groups in dynamic systems; for example, all nine hydrogens of a tert-butyl group are agostically interacting with ruthenium on the NMR timescale at 20 degrees C.
