Abstract The Complexes [RuIV(terpy)(cxhn)O](ClO4)2 (cxhn = N,N,N′,N′-tetramethyl-1,2-diaminocyclohexane, terpy = 2,2′:6′,2′′(terpyridine) and RunIV(Me3tacn)(cbpy)O](ClO4)2 (cbpy = (−)-3,3′-[(4S-trans)-1,3-dioxolane-4,5-dimethyl]-2,2′-bipyridine and Me3tacn = 1,4,7-trimethyl-1,4,7-triazacyclononane) have been prepared and crystal structures of [RuIV(terpy)(cxhn)O](ClO4)2 and [RuII(Me3tacn)(3,3′Me2bpy)(OH2)](ClO4)2
所有
钌-氧配合物都与烯烃反应,生成相应的
环氧化物。[RuIV(terpy)(1R,2R-cxhn)O](
ClO4)2对
苯乙烯和
4-氯苯乙烯的
化学计量氧化得到相应的
环氧化物,没有对映体过量。使用[RuIV(Me3tacn)(cbpy)O]( )2,在
苯乙烯和
4-氯苯乙烯的氧化中分别发现9%的对映体过量的R-
苯乙烯氧化物和R-4-
氯代
苯乙烯氧化物。
