Reaction of [ReOCl3(PPh3)2] or [ReO2I(PPh3)2] with 2,2'-diphenylglycine (dpgH2) in refluxing ethanol afforded the air-stable complex [ReO(dpgH)(dpg)(PPh3)] (1). Treatment of [ReO(OEt)I2(PPh3)2] with 1,2,3-triaza-7-phosphaadamantane (PTA) afforded the complex [ReO(OEt)I2(PTA)2] (2). Reaction of [ReOI2(PTA)3] with dpgH2 led to the isolation of the complex [Re(NCPh2)I2(PTA)3]·0.5EtOH (3·0.5EtOH). A similar
[ReOCl3(PPh3)2]或[ReO2I(PPh3)2]与2,2'-二苯基甘氨酸(dpgH2)在回流的乙醇中反应,得到空气稳定的络合物[ReO(dpgH)(dpg)(PPh3)](1 )。用1,2,3-三氮杂-7-磷金刚烷(PTA)处理[ReO(OEt)I2(PPh3)2]得到复合物[ReO(OEt)I2(PTA)2](2)。[ReOI2(PTA)3]与dpgH2的反应导致分离出[Re(NCPh2)I2(PTA)3]·0.5EtOH(3·0.5EtOH)。使用[ReOX2(PTA)3](X = Cl,Br)进行类似的反应,得到类似的卤化物络合物[Re(NCPh2)Cl2(PTA)3]·2EtOH(4·2EtOH)和[Re(NCPh2)( (PTA)3 Br 2]·1.6EtOH(5·1.6EtOH)。用苯甲酸(2,2'-二苯基乙醇酸,benzH)和2得到配合物[ReO(苯)2(PTA)]
