hydrodisilanes, R3SiSiMe2H (2; R = alkyl, aryl), as reductants for N,N-dimethylformamide (DMF) in the presence of (Me3N)Mo(CO)5 as a catalyst led to the formation of a series of novel and structurally interesting siloxanes as well as trimethylamine. In the case of 1 the cyclic poly(dimethylsiloxanes) D4 and D6 are obtained, and for 2 the products are bis(disilyl) ethers, (R3SiSiMe2)2O. Siloxymethylamine
在(Me 3 N)存在下,使用HSiMe 2 OSiMe 2 H(1)和各种氢化乙硅烷R 3 SiSiMe 2 H(2 ; R =烷基,芳基)作为N,N-二甲基甲酰胺(DMF)的还原剂Mo(CO)5作为催化剂导致形成了一系列新颖的和结构上令人感兴趣的硅氧烷以及三甲胺。在1的情况下,获得环状聚(二甲基硅氧烷)D 4和D 6,而对于2的产物是双(二甲硅烷基)醚,(R 3 SiSiMe 2)2个从DMF的初始氢化硅烷化所得O. Siloxymethylamine中间体,(ME 2 NCH 2 OSiMe 2)2 O(3)和R 3 SiSiMe 2 OCH 2 NME 2(4 ; R = Me中,PH),从反应1和2,可以分别观察到,在的情况下3,分离和纯化。在各自的起始硅烷和催化剂的存在下,中间体容易反应形成合适的硅氧烷材料和三甲胺。通过与R反应将化合物3官能化3 ECl(E = Si,Ge,R
