Compound Et3SiOCH2NMe2 transfers Me2NCH2 to R2NH (R2=Et2, PhMe, [Cr(η6-C6H5)(CO)3]Me, PhH) to form previously unknown diaminomethanes, Me2NCH2NR2 and, in the case of R2=PhH, the triamine Me2NCH2N(Ph)CH2NMe2. The diaminomethanes exhibit an unreported disproportionation to a mixture of (R2N)2CH2, (Me2N)2CH2, and Me2NCH2NR2, which can be trapped as their [Mo(CO)4(diamine)] complexes. Whereas PhMeNCH2NMe2 is a labile material, the metal-substituted ([(η6-C6H5)Cr(CO)3]MeNCH2NMe2 is a stable material. The triamine Me2NCH2N(Ph)CH2NMe2 is unstable with respect to transformation to 1,3,5-triphenyltriazine, but is readily trapped as the bidentate-triamineMo(CO)4. All metal complexes were characterized by single-crystal X-ray diffraction.

Reaction of d0 Zr(NMe2)2[MeC(N iPr)2]2 (1) with O2 at -30°C gives three Zr containing products: a peroxo trimer {(μ-η2: η2-O2)Zr[MeC(NiPr)2] 2}3 (2), an oxo dimer {(μ-O)Zr[MeC(N iPr)2]2}2 (3), and an oxo polymer {(μ-O)Zr[MeC(NiPr)2]2}n (4). 2 is a rarely observed peroxo complex from the reaction of a d0 complex with O2.
