Reaction of tetrahydrofurfuryl chloride and sodium cyclopentadienide has been found to yield tetrahydrofurfurylcyclopentadiene, I, which is converted to its thallium salt, II, by thallium ethoxide. II reacts with BrMn(CO)5 and [ClRh(CO)2]2 to give the corresponding tetrahydrofurfurylcymantrene, III, and both tetrahydrofurfurylcyclopentadienyl rhodium dichloride, IV, and its dinuclear species, V. 2-D
已经发现四氢糠基氯与环戊二烯酸钠的反应产生四氢糠基环戊二烯,I,其被乙醇th转化为its盐,II。II进行反应与BrMn(CO)5和[ClRh(CO)2 ] 2,得到相应的tetrahydrofurfurylcymantrene,III,和两个tetrahydrofurfurylcyclopentadienyl二氯化铑,IV,和它的双核物种,V. 2- d的的COZY分析1V的1 H NMR光谱允许分配所有共振。锰配合物作为Nujol溶液在77 K下进行光解,可产生一氧化碳,同时得到四氢糠基环戊二烯基锰二羰基和该二羰基物种的第二个异构体,其中四氢糠基侧基与金属结合。前一过程的光化学和热逆转产生III和更多的四氢糠基结合的配合物,而后一过程的逆转仅在升温至更高温度时观察到。这是首次在低温基质实验中观察到与这种远程配体的分子内反应。
