Abstract The reactions of platinum bis(n-propylxanthate), Pt(S 2 CO n Pr) 2 (Pt(xan) 2 ) with a number of potentially bidentate Group 15 and mixed Group 15/Group 16 donor ligands (L-L′) have been investigated in dichloromethane solution. The products of the reactions have been identified by multinuclear ( 31 P, 77 Se, 195 Pt) magnetic resonance, infrared and analytical studies. When reactions in 1:1 molar
摘要双(正丙基黄原酸酯)铂,Pt(S 2 CO n Pr)2(Pt(xan)2)与许多潜在的双齿15族和15/16族混合供体配体(LL')的反应具有在二氯甲烷溶液中进行了研究。反应的产物已经通过多核(31 P,77 Se,195 Pt)磁共振,红外和分析研究进行了鉴定。当在室温下以1:1摩尔比例进行反应时,通常会置换一种黄药配体以生成[(LL')Pt(xan)] +,然后进一步反应以生成二硫代碳酸酯络合物(LL')Pt(S 2 CO)和黄原酸酯。如果反应在低温下进行,则避免该反应,并且温度依赖性等式为(η1 -LL')Pt(η1 -xan)(η2 -xan)⇌[(η2 -LL')Pt (η2 -xan)] + + xan-的出现是由于各种配体的相似供体能力。二硫代碳酸酯是铂的强于黄药的配体,因此在该配体下不会发生这些反应。
