| 概要 |
The first organoruthenium amidinates bearing a Ru-C σ bond were prepared, and their structures were elucidated by spectroscopy and crystallography. A halogenoruthenium amidinate precursor, [(η^6-C_6H_...6)Ru(η-^tBuNCPhN^tBu)Cl], was treated with Grignard reagents to form thermally and air stable alkyl ruthenium complexes, [(η^6-C_6H_6)Ru(η-^tBuNCPhN^tBu)R] (R=Me (3a), Et (3b), Bn (3c)). C_s-symmetric 'piano stool' structures of these complexes were suggested from NMR spectroscopic data. These were supported by crystallographic studies of 3b and 3c.続きを見る
