- W2393096253 abstract "Treatment of the europium complex[(Me3Si)2N]3Eu(μ-Cl)Li(THF)3 with 2-(2,4,6-Me3C6H2N=CH)C4H3NH afforded a trivalent europium metal complex with formula [2-(2,4,6-Me3C6H2N=CH)C4H3N]3Eu(THF).A series of guanidine products were synthesized by the reaction of aromatic amines to N,N′-diisopropylcarbodiimide with the europium complex as catalyst.The influence of the conditions such as reaction time,temperature,catalyst loading and solvent on the reaction was studied.The results showed that the europium complex exhibited a high catalytic activity and that the guanidine products were obtained beyond 80%yields in the following conditions:the molar ratio of the catalyst loading was 2%mol,the solvent was THF,the temperature was 60℃,and the time was 8 h." @default.
