The triplatinum compound [Pt3(CNBut)6] reacts with the alkynes RCCR (R = Ph, C6H4Me-4, or C6F4OMe-4) in toluene at 100 °C to give platinacyclopenta-2,4-diene complexes [[graphic omitted](R)}(CNBut)2], and with C2(CO2Me)2 at 40 °C to afford the diplatinacyclohexa-2,5-diene compound [[graphic omitted](CO2Me)}(CNBut)4]. Bis(cyclo-octa-1,5-diene)platinum reacts with RCCR (R = C6F4OMe-4 or CO2Me) to afford
雷公藤二甲酸酯化合物[Pt 3(CNBu t)6 ]与炔烃RC CR(R = Ph,C 6 H 4 Me-4或C 6 F 4 OMe-4)在甲苯中于100°C反应,生成platinacyclopenta- 2,4-二烯配合物[[省略图示](R)}(CNBu t)2 ],并在40°C下与C 2(CO 2 Me)2结合,得到二铂环己基-2,5-二烯化合物[省略](CO 2 Me)}(CNBu t)4 ]。双(环八-1,5-二烯)铂与RC CR反应(R = C 6 F 4得到OMe-4或CO 2 Me),得到化合物[cod =环-八-1,5-二烯)。非对称炔烃MeC CCO 2 Me在25°C下与[Pt 3(CNBu t)6 ]反应,得到[[图解省略](CO 2 Me)}(CNBu t)4 ]和[Pt(cod)2 ]以产生铂环戊二烯异构体的混合物[[图中省略](R 5)}(cod)](R 2 =
