The catalytic behaviors of Dy (OTf)3, DyCl3 and rare earth diphosphonate complex {[Dy(OTf)2L2(H2O)2](OTf)(CH3CN)}[L=(iPrO)2P(O)CH2P(O)(iPrO)2] were studied for Maanich reactions. The results showed that the yield of 54% ,8% and 47% were obtained over Dy(OTf)3, [Dy(OTf)2L2(H2O)2](OTf)(CH3CN) and DyCl3, respectively. Among the twelve rare earth chlorides involved, ErCl3 attained the maximum yield 0f 61% for Mannich reactions.
