Chlorodimethylphenylsilane Usage And Synthesis

Chemical Properties

clear colorless to light yellow liquid

Uses

Chlorodimethylphenylsilane is used in the synthesis of enantioenriched allenylsilanes through an ortho-ester Claisen rearrangement of chiral and silylpropargylic alcohols.

Purification Methods

Fractionate it through a 1.5 x 18inch column packed with stainless steel helices, or a spinning band column. [Daudt & Hyde J Am Chem Soc 74 386 1952, Lewis et al. J Am Chem Soc 70 1115 1948, Eaborn J Chem Soc 494 1953.] It is used for standardising MeLi or MeMgBr which form Me3PhSi which is estimated by GC. [Maienthal et al. J Am Chem Soc 76 6392 1954, House & Respess J Organomet Chem 4 95 1965, Beilstein 16 IV 1475.] TOXIC and MOISTURE SENSITIVE.
