DI-TERT-BUTYLDICHLOROSILANE Usage And Synthesis
- Purification MethodsPurify it by fractional distillation. 20 1.01. It is a colourless liquid with a pleasant odour and does not fume in moist air, but does not titrate quantitatively with excess of dilute alkali. [Tyler et al. J Am Chem Soc 70 2877 1948.] Di -tert-butyl silyl bis(trifluoromethanesulfonate) [85272 -31 -7] M 440.5, b 73.5 -7 4 . 5o/0.35mm, d 4 Purify it by fractional distillation at high vacuum. 20 1.36 (see pK for triflic acid). It is a pale yellow liquid which should be stored under argon. It is less reactive than the diisopropyl analogue. The presence of the intermediate monochloro compound can be detected by 1H NMR, (CHCl3): tert-Bu2Si(OTf)2 [ 1.25s], but impurities have 1.12s for tert-Bu2Si(H)OTf and 1.19s for tert-Bu2HSi(Cl)OTf.
