Ni(CO)3 complexes ligated by an isolable cyclic (alkyl)(amino)silylene (CAASi) or an isolable cyclic dialkylsilylene (CDASi) were synthesized by the reaction of the corresponding Ni(dvtms) complex (dvtms = 1,1,3,3-tetramethyl-1,3-divinyldisiloxane) with CO to estimate the donor strengths of CAASi and CDASi. The CO stretching frequencies (Tolman electronic parameters, TEP) of the Ni(CO)3 complexes indicate that the net donating ability of CDASi and CAASi to Ni(CO)3 are almost the same and in between PPh3 and P(tBu)3. The DFT calculations suggested that the TEP values are mainly correlated with the energy level of the lone pair orbital of the ligand but not strongly associated with those of the vacant π-accepting orbitals.
