苯氧基稀土二氯化合物的合成

SYNTHESIS OF PHENOXY LANTHANIDE DICHLORIDES

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),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.

New lanthanide compounds with the general formula CHO LnCl·nTHF(Ln=Pr,Nd,Sm,Gd;n=0,1,2,3,4)have been prepared and characterized by elemental analyses,thermal analysis and infrared spectroscopy.The major infrared absorption peaks of the above compounds appear at 2970,2800,1600,1460,1015,920,860,480 cm.The absorptions at 1015 and 1065 cmare consi-dered to be the characteristics of phenoxy group and tetrahydrofuran molecule respec-tively.
