实验步骤: To 6.7 g of 2,2-dimethyl-3-(2-oxopropyl)cyclopropylacetaldehyde at 0° C. was added 5.2 g of trimethylsilyldimethylamine over a 5 min period. The resulting product was distilled through a spiral bantamware column to yield 6.7 g of the desired product having a boiling point of 85°-90° at 1 mm Hg. The resulting product was distilled through a spiral bantamware column

实验步骤: 20 ml of dry chloroform and 1.85 g (15.78 mmol) of N,N-dimethyltrimethylsilylamine are added to 6.23 g (14.27 mmol) of bis(dimethylamino)chlorocarbenium bis(pentafluoroethyl)phosphinate. The reaction mixture is stirred for 1 hour at room temperature, and all volatile products are removed under reduced pressure. The residue is subsequently dried at 7.0 Pa and an oil-bath temperature of 50° C. for 1 hour, giving 6.29 g of hexamethylguanidinium bis(pentafluoroethyl)phosphinate, corresponding to a yield of 99%. all volatile products are removed under reduced pressure The residue is subsequently dried at 7.0 Pa and an oil-bath temperature of 50° C. for 1 hour

实验步骤: 10 ml of dry chloroform and 1.29 g (11.00 mmol) of N,N-dimethyltrimethylsilylamine are added to 2.45 g (9.93 mmol) of bis(dimethylamino)chlorocarbenium methylsulfate. The reaction mixture is stirred for 1 hour at room temperature, and all volatile compounds are subsequently removed under reduced pressure. The residue is dried for a further 1 hour under reduced pressure at 7.0 Pa and an oil-bath temperature of 50° C., giving 2.42 g of hexamethylguanidinium methylsulfate, corresponding to a yield of 95.5%. all volatile compounds are subsequently removed under reduced pressure The residue is dried for a further 1 hour under reduced pressure at 7.0 Pa and an oil-bath temperature of 50° C.
