Zn(II) and Co(II) organometallic complexes I and II involving 1,2-ethylenediamine were first synthesized from
the reaction of the ligand 1,2-ethylenediamine with Zn(OAc)2· 2H2O and Co(OAc)24H2O in ethanol, then they were used
to catalyze the Henry reaction, and good catalytic results (64-99%) were achieved.
Keywords: Zn(II) and Co(II)organometallic complexes, 1, 2-ethylenediamine, the Henry reaction, catalytic activity
