摘    要:在研究稀土金属氯化物对Mannich反应的催化作用基础上,进一步研究了部分稀土氯化物与单膦氧配体、三苯氧膦(Ph_3PO)以及两种双膦酸酯、四异丙基亚甲基双磷酸酯{(~iPrO)_2P(O)CH_2P(O)(~iPrO)_2=L]}及双二苯基膦氧甲烷{Ph_2P(O)CH_2P(O)Ph_2]=dppmO_2}所形成的配合物对Mannich反应的催化作用。结果发现,膦氧配体与稀土氯化物的配合物的催化能力比相应的氯化物低,但GdCl_3和TmCl_3与L(物质的量比1:1)结合时所形成的配合物的催化能力没有下降。

Abstract:The catalytic behaviors of some rare earth complexes with the phosphonate ligands, containing both monophosphonate and diphosphonate ligands, were investigated on the basis of researches on the catalysis of rare earth chloride for Mannich reactions. The results showed that the catalytic behaviors of the complex consisted of rare earth chloride + phosphonate ligands ( LnCl3 + L) were lower than that of corresponding rare earth chloride except the complexes of GdCl3 and TmCl3 with the ligand L = (^iPrO) 2 P (O) CH2 P (O) ( ^iPrO ) 2 ] ( molar ratio of LnCl3 to L = 1 : 1 ).
