Abstract

The sterically encumbered polymeric dialkyl complexes [M(CH2SiMe3)(2)](infinity) [M = Mg, Mn-II] were deaggregated by the potent two-electron sigma-donor, 1,3-bis(2,6-diisopropylphenyl)-imidazol-2-ylidene (IPr), to yield the first examples of the monomeric three-coordinate [M(CH2SiMe3)(2)]center dot donor complexes [M = Mg (1); Mn (2)]. Similarly, monomeric three-coordinate species M[CH(SiMe3)(2)](2)center dot IPr [M = Mg, (3); Mn, (4)] were obtained from the bulkier disilyl-substituted alkyl [CH-(SiMe3)(2)] congeners M[CH(SiMe3)(2)](2)center dot ether by displacement of the ether by IPr. Complexes 1-4, which represent rare examples of N-heterocyclic-carbene-stabilized dialkylmagnesium and dialkylmanganese species, were crystallographically characterized; the diamagnetic magnesium complexes were also characterized in an arene solution by H-1 and C-13 NMR spectroscopy.
