The synthesis of a number of platinum(II)-dioxolene complexes of the type [PtO-[graphic omitted]O}L2] was readily achieved in high yields via the silver(I) oxide-mediated reactions of the cyclic α,β-diketone compounds [graphic omitted]H(CO2R)(X = CH2, O or S) with platinum(II) chloride complexes cis-[PtCl2L2][L = PPh3 or L2= cycloocta-1,5-diene (cod)]. The complexes can be considered to be derived
通过氧化银(I)介导的环状α反应可轻松以高收率合成许多[Pt O- [图解省略] O} L 2 ]类型的铂(II)-二氧戊烯络合物,β-二酮化合物[未显示图形] H(CO 2 R)(X = CH 2,O或S)与氯化铂(II)的配合物顺式-[PtCl 2 L 2 ] [L = PPh 3或L 2=环辛基-1,5-二烯(cod)]。该络合物可以被认为衍生自环戊二烯,呋喃或噻吩,并且与金属儿茶酚酸盐有关。对衍生自环戊二烯的络合物[Pt O [图省略] O}(PPh 3)2 ]的单晶结构测定表明存在平面的铂-氧杂环丁烷环系统。氧化银(I)也可用于以高收率和高纯度合成相关的四氯邻苯二酚配合物[Pt(1,2-O 2 C 6 Cl 4)L 2 ](L = PPh 3或L 2 = cod)。
