| DIMETHYLTHEXYLSILYL CHLORIDE Usage And Synthesis |
| Chemical Properties | clear colorless to almost colorless liquid |
| Physical properties | mp 14–15 °C; bp 55–56 °C/10 mmHg; d 0.909 g cm?3. |
| Uses | Silylating reagent for the protection of 1? and 2? alcohols and N-silylation of amines and amides; used in the preparation of thexyldimethylsilyl triflate; formation of α-silyl hydrazones; formylation of polyfluoroalkyl halides. Thexyldimethylsilyl chloride (TDS-Cl) was first introduced as a more easily prepared alternative to the more commonly used t-butyldimethylsilyl chloride for the protection of alcohols. |
| Uses | Protecting reagent for alcohols and other functional groups. Employed in the synthesis of silicon naphthocyanine and cyclodextrin derivatives, which are useful as antitumor dyes and chiral stationary phases, respectively. |
| Preparation | To a mixture of dimethylchlorosilane (10 mL, 92 mmol) and AlCl3 (0.680 g, 5 mmol) at 25°Cwas added 2,3-dimethyl-2-butene (11 mL, 91 mmol). After stirring for 4 h at ambient temperature, the mixture was filtered and distilled to yield 15.2 g of TDS-Cl (93%). |
| Purification Methods | Purify it by fractional distillation and store it in small aliquots in sealed ampoules. It is very sensitive to moisture and is estimated by dissolving an aliquot in excess of 0.1M NaOH and titrating with 0.1M HCl using methyl red as indicator [Szabó et al. Helv Chim Acta 67 2128 1984]. |
