The synthesis and characterization of the O-donor ligated, air and water stable organometallic complexes trans- (2), and cis-(hfac-O,O)2Rh(CH3)(py) (3), trans-(hfac-O,O)2Rh(C6H5)(py) (4), cis-(hfac-O,O)2Rh(C6H5)(py) (5), and cis-(hfac-O,O)2Rh(Mes)(py) (6) (where hfac-O,O = κ2-O,O-1,1,1,5,5,5-hexafluoroacetylacetonato) are reported. These compounds are analogues to the O-donor iridium complexes that
O-供体连接的,对空气和水稳定的有机金属配合物反式-(2)和顺式-(hfac-O,O)2 Rh(CH 3)(py)(3),反式-(hfac )的合成与表征-O,O)2 Rh(C 6 H 5)(py)(4),顺式(hfac-O,O)2 Rh(C 6 H 5)(py)(5)和顺式(hfac- O,O)2的Rh(MES)(PY)(6)(其中HFAC-O,O =κ 2报道了-O,O-1,1,1,1,5,5,5-六氟乙酰丙酮。这些化合物是O-供体铱配合物的类似物,O-供体铱配合物是加氢芳基化反应和CH-H活化反应的活性催化剂,以及我们最近报道的双乙酰丙酮铑配合物。的反式-配合物2所经历的定量反式到顺式异构化在环己烷中,以形成3,其激活的C-H键在两个苯和均三甲苯形成化合物5和6分别。所有这些化合物对空气和水都是稳定的,不会导致分解产物。复杂5 促进苯进行苯乙烯的加氢芳基化反应,生成二氢sti。
