12 ROAD MAP: Compound A has the chemical formula CHn. Treatment of A with H,SO, and HO produces sertiary alcohol B. However, when A undergoes hvdroboration with 9-BBN followed by oxidation secondary alcohol C is formed. When Compound A is reacted with HCl alkyl halide D is produced. When D is reacted with water at room temperature alcohol B is produced. When Compound D is reacted with sodium methoxide in TH at room temperature, no reaction occurs. Upon treatment of...

16. ROAD MAP: Compounds A, B, and Care constitutional isomers. Treatment of A or B with potassium tert-butoxide gives the same alkene D. If the base is changed to a less sterically hindered base such as sodium ethoxide, A and C give the same alkene E as the major product. Treatment of C (spectroscopic data given on next page) with potassium tert-butoxide gives yet another alkene F as a minor product. Compound B reacts...

Compound A (C11H16O) has a band in the IR spectrum at 3450 cm-1 (strong, broad) and does not react with pyridinium chlorochromate (PCC) in CH2CI2. Compound A does react with HBr to give compound B (11H15Br). Compound B reacts with potassium f-butoxide to give compound C (C11H14). Ozonolysis of C followed by treatment with Zn and water gives CH3CHO and compound D (C9H10O). The proton NMR spectrum of compound D is given below. Treatment of compound D with ethyl magnesium...

Problem #23: When compound X (C,H,Br) is reacted with sodium cyanide (NaCN) forms compound Y (C,H,N). Compound Y, upon reduction with H over a Ni catalyst, yields compound Z (C,HIN. The 'H NMR spectrum of X gives two signals, a multiplet at δ = 7.3 ppm (5H) and a singlet at δ 4.25 ppm (2H). The 'H NMR spectrum of Y is similar to that of X in that it shows a multiplet at ö-7.3 ppm (5H) and a singlet...
