Mehrotra 等人曾报道三烷氧基稀土化合物与乙酰氯反应,合成烷氧基稀土一氯或二氯化合物,Misra 等人以三异丙氧基稀土化合物[Ln(OPr-i)_3,Ln=Nd,Pr]与苯酚在苯溶剂中反应,制备了三苯氧基稀土化合物,但有关苯氧基稀土二氯化合物的合成迄今未见报道. Mehrotra et al. Reported that trialkoxy rare earth compounds reacted with acetyl chloride to synthesize alkoxyl rare earth monochloride or dichloro compounds. Misra et al. Used triisopropoxy rare earth compounds [Ln (OPr-i) 3, Ln = Nd, Pr] reacted with phenol in benzene solvent to prepare triphenoxy rare earth compound, but the synthesis of phenoxy rare earth dichloride has not been reported so far.
