化合物 Et3 SiOCH2 NMe2 将 Me2 NCH2 转移至 R2 NH (R2 = Et2 , PhMe, [Cr(η(6) -C6 H5 )(CO)3 ]Me, PhH) 形成以前未知的二氨基甲烷 Me2 NCH2 NR2 ，在 R2 = PhH 的情况下，形成三胺 Me2 NCH2 N(Ph)CH2 NMe2 。二氨基甲烷表现出未报道的歧化反应，形成 (R2 N)2 CH2 、(Me2 N)2 CH2 和 Me2 NCH2 NR2 的混合物，其可以作为它们的 [Mo(CO)4 (二胺)] 络合物被捕获。 PhMeNCH2 NMe2 是一种不稳定的材料，而金属取代的 ([(η(6) -C6 H5 )Cr(CO)3 ]MeNCH2 NMe2 是一种稳定的材料。三胺 Me2 NCH2 N(Ph)CH2 NMe2 在转化为 1,3,5-三苯基三嗪方面不稳定，但很容易被捕获为二齿三胺 Mo(CO)4 。所有金属配合物的特征为单晶X射线衍射。
Compound Et3 SiOCH2 NMe2 transfers Me2 NCH2 to R2 NH (R2 =Et2 , PhMe, [Cr(η(6) -C6 H5 )(CO)3 ]Me, PhH) to form previously unknown diaminomethanes, Me2 NCH2 NR2 and, in the case of R2 =PhH, the triamine Me2 NCH2 N(Ph)CH2 NMe2 . The diaminomethanes exhibit an unreported disproportionation to a mixture of (R2 N)2 CH2 , (Me2 N)2 CH2 , and Me2 NCH2 NR2 , which can be trapped as their [Mo(CO)4 (diamine)] complexes. Whereas PhMeNCH2 NMe2 is a labile material, the metal-substituted ([(η(6) -C6 H5 )Cr(CO)3 ]MeNCH2 NMe2 is a stable material. The triamine Me2 NCH2 N(Ph)CH2 NMe2 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.
