dienes like N-substituted 4,5-dimethylene-2-oxazolidinones a and b, and KTpMe2 yields derivatives of the composition TpMe2Ir(a or b) (1a,b). Derivative 1a reacts with Ph2PC⋮CPPh2, with the formal oxidative addition of the diene moiety to the metal center and coordination of the phosphine in the κ1 mode. Derivatives 1a,b react with aromatic aldehydes to form the new compounds 3 (with benzaldehyde) and
二聚体[Ir(μ-Cl)(coe)2 ] 2与两个环外二烯如N-取代的4,5-二亚甲基-2-恶唑烷二酮a和b的反应,以及KTp Me2产生组成为Tp Me2 Ir的衍生物(a或b)(1a,b)。衍生物1A的Ph发生反应2 PC⋮CPPh 2,与正式氧化加成二烯部分的磷化氢的金属中心,并协调在κ 1模式。导数1a,b与芳族醛反应形成新化合物3(与苯甲醛)和4(茴香醛),其中包含由两个有机片段(二烯和醛)偶联形成的精心设计的二齿配体。化合物3a,b的结构已经通过X射线衍射分析确定。
