R-Butyldimethylchlorosilane

As(III) and As(V) compounds. Comparison with T-ECgTLtMgBr derivatization with A-r-butyldimethylsilyl-A-methyltrifluoroacetamide with 1% r-butyldimethylchlorosilane. ... [Pg.303]

Transsilylation. Several reagents have been recommended for preparation of /-butyldimethylsilyl ethers by transsilylation. These include allyl-r-butyldimethyl-silane and /-butyldimethylsilyl enol ethers of pentane-2,4-dione and methyl aceto-ucelate,2 both prepared with r-butyldimethylchlorosilane and imidazole. Unlike the reaction of r-butyldimethylchlorosilane with alcohols, which requires a base catalyst, these new reagents convert alcohols to silyl ethers under slightly acidic conditions (TsOH) in good yield. The trimethylsilyl ethers of pentane-2,4-dione and methyl acetoacetate convert alcohols to trimethylsilyl ethers at room temperature even with no catalyst. The former reagent is also useful for silylation of nucleotides.3... [Pg.62]
