Chemical reactions induced by recoil implantation were studied focussing on parent type species in tris(β-diketonato)metal(III) complexes. The yield of the substitution reaction *M + M(acac)3 →*M(acac)3 + M was dependent on the force constant ratio K(*M —0)/K(M — O), showing that competition occurred between *M and M in the cage of the acetylacetonate complex. In the case of *Cr implantation in Co(acac)3, an exceptionally large yield could be explained by formation of Co(acac)2, whose central metal easily exchanges with *Cr, and by pickup of acac. When different β-diketonate complexes were examined in the reaction *Cr + M(β —dik)3 →*Cr(β-dik)3 + M the yield was dependent on the stability of the M(β — dik)3 complexes. A reaction model to explain these results reasonably was presented.
