- the proportion of trimethylsilane is low and the yield is the raw material 3, 3, 3-trifluoropropyne 2.0 to 6.3% And very low. It has not yet been possible to purify and isolate the mixture. Since the hydrosilylation reaction is obtained as a mixture with isomers, the yield is low, and further, there is a problem that separation is difficult and industrial utility value is low.
- gaseous acetylene compounds there is a danger, and there is a problem when there are restrictions on the materials of containers that can be used.
- the reaction solvent yields the target silane silane of the general formula (1) in a high yield.
- the vinylsilane represented by the general formula (1) is not desirable when a low-boiling solvent such as tetrahydrofuran is used as a reaction solvent because it is difficult to separate the reaction product from the solvent.

If the temperature is less than 20 ° C, the reaction rate is slow, and the reaction tends not to proceed sufficiently. On the other hand, if it exceeds 120 ° C, the yield of the target silane is reduced, and the proportion of the reduction product tends to increase, which is not preferable.
- the reactor may be an open-air reactor, or a closed reactor such as an autoclave.
- the reaction pressure can be under atmospheric pressure or under pressure. 0 ⁇ 0.20MPa (gauge pressure) is preferred! / ,.
- the reaction product can be purified directly or after adding water. It can be isolated and purified by distillation under normal pressure or under reduced pressure. You can get things.
- Example 3 the same reaction was carried out except that 2 bromo-3, 3, 3 trifluoropropene 4. Og (23 mmol) was added and the reaction was conducted at a reaction temperature of 50 ° C for 41 hours. The 19 F-NMR internal standard yield of (1 trifluoromethylvinyl) trimethylsilane was 42%.
- Example 5
- Example 3 the same reaction was carried out except that 2 bromo-3, 3, 3 trifluoropropene 4. Og (23 mmol) was added, followed by reaction at 5 ° C for 120 hours. The 19 F-NMR internal standard yield of (1 trifluoromethylvinyl) trimethylsilane was 50%.
- Example 6
- Example 3 1, 3 dimethyl-2 imidazolidinone 28 mL, aluminum 0.23 g
- NMP N-methyl-2-pyrrolidone
- the vinyl silane compound is used as a raw material in the method for producing vinyl silane of the present invention, it is possible to obtain butyl silane as a main product in a safe and easy manner with a high yield, and industrial use. Value is high.
