DIISOPROPYLCHLOROSILANE Usage And Synthesis

Physical properties

bp 150–153°C,bp 54–55°C/45 mmHg; d 0.872 gmL?1

Uses

Intramolecular hydrosilylation is also possible within β-diisopropylsilyloxy esters (13), constituting an exceptionally mild method for reducing ester groups to the aldehyde oxidation level (eq 4).The derivatives (13) may be synthesized from β-hydroxy esters (12) as described above for the analogous ketones. Treatment with fluoride ions (but not Lewis acids) induces hydride transfer to give alkoxysiladioxanes (14) in excellent yields (≥95%). Although usually performed in dichloromethane, the hydrosilylation may also be accomplished with ethyl acetate as solvent, providing strong evidence for intramolecularity.

Preparation

obtained by reaction of trichlorosilane with isopropylmagnesium chloride;the original yield of 45% may be raised to 70–80% by employing conc hydrochloric acid to quench the reaction.

Application

Used in a silylation-reduction-allylation sequence of β-hydroxy esters to homoallylic-substituted 1,3-diols. Used in the silylation-hydrosilation-oxidation of allyl alcohols to 1,3-diols. Reaction carried out in diastereoselective manner. Reduces β-hydroxy ketones to anti-1,3 diols.

Purification Methods

Impurities can be readily detected by 1H NMR. Purify it by fractional distillation [Gilman & Clark J Am Chem Soc 69 1499 1947, Allen et al. J Chem Soc 3668 1957].
