WebApr 7, 2024 · The Tollens reagent \(\left( \ce{Ag(NH_3)_2^+} \right)\) is a mild oxidizing agent that can oxidize aldehydes, but not alcohols or other carbonyl compounds. A positive test result is the formation of elemental silver (Figure 6.76), which precipitates out as a "silver mirror" on the test tube, or as a black colloidal precipitate. ... The standard preparation for n-BuLi is reaction of 1-bromobutane or 1-chlorobutane with Li metal: 2 Li + C4H9X → C4H9Li + LiX (X = Cl, Br) If the lithium used for this reaction contains 1–3% sodium, the reaction proceeds more quickly than if pure lithium is used. Solvents used for this preparation include benzene, cyclohexane, and diethyl ether. When BuBr is the precursor, the product is a homogeneous solution, consisting of …
