clear colorless to light yellow liquid
Chlorodimethylphenylsilane is used in the synthesis of enantioenriched allenylsilanes through an ortho-ester Claisen rearrangement of chiral and silylpropargylic alcohols.
Chlorodimethylphenylsilane can be used for nucleophilic silylation; alcohol derivatization; antenna chromophores; enolate capture; and Kumada-FlemingTamao oxidation.
Like other chlorosilanes, this compound can be destructive to tissue of the mucous membranes, upper respiratory tract, eyes and skin. Store in a cool dry place; the compound is moisture sensitive.
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.
