The Raman spectra of CH3Cl2SiSiCl2CH3 and CD3Cl2SiSiCl2CD3 between 3000 and 30 cm-1 have been recorded at various temperatures. The infrared spectra at ambient temperature were recorded from 3000 to 50 cm-1. Both isotopomers exist as a mixture of gauche and anti rotamers at room temperature. The energy difference E(anti)-E(gauche) was determined from the Raman spectra as being -0.9 ± 0.2 kJ mol-1 for CH3Cl2SiSiCl2CH3 and -1.2 ± 0.2 kJ mol-1 for CD3Cl2SiSi2CD3. Assisted by ab initio calculations, the vibrational spectra have been assigned using C(2h) symmetry for the anti rotamers and C2 symmetry for the gauche rotamers. Scaled and unscaled harmonic frequencies and harmonic symmetry force constants have been reported for both rotamers, and normal coordinate analyses have been carried out. Potential energy distributions have been reported.

Paragraph 0084-0086, (2020/05/06)
PROBLEM TO BE SOLVED: To construct a technique which can simply, efficiently and inexpensively synthesize a silyl sodium compound in a small number of processes and in a short time, especially to construct a technique which synthesizes a silyl sodium compound by using easily available reagents from a viewpoint of sustainability without using reagents which are difficult to handle and are toxic. SOLUTION: There is provided a method for synthesizing a silyl sodium compound comprising a step of reacting a dispersion obtained by dispersing a silyl halide compound or a disilane compound with sodium into a dispersion solvent, the silyl halide compound or the disilane compound as a starting compound, in a reaction solvent to obtain the silyl sodium compound. There is also provided a method for deoxidizing an epoxy compound comprising a step of reacting the silyl sodium compound obtained by synthesizing method of the silyl sodium compound with an epoxy compound to deoxidize the epoxy compound to stereoselectively produce an alkene compound.

Paragraph 0025; 0026; 0027-0030; 0041-0062; 0065-0088, (2018/05/16)
The invention discloses a method for continuously preparing disilane compounds by a micro-reaction device. The method comprises the following steps: (1) a solution A is prepared from organosilane by dissolving in a first organic solvent, or is organosilane; (2) a solution B is prepared from an oxidant by dissolving in a second organic solvent, or is an oxidant; (3) the solution A and the solutionB are pumped into a micro-mixer of the micro-reaction device simultaneously for mixing, a product then flows into a microreactor of the micro-reaction device for reaction, and the disilane compounds are prepared, wherein the microreactor is filled with a catalyst. Raw materials required in the method are easily available and have better stability, metal copper compounds are used as a catalyst forcoupling reaction on trisubstituted silanes, and the coupling effect on trisubstituted silanes is better than that of alkali metal catalysts and transition metal catalysts; a micro-channel reactor issuitable for an exothermic coupling reaction due to good mixing and heat transfer performance.
