Which halides are unreactive in a Friedel-Crafts alkylation reaction? What is the major product obtained from hydroboration-oxidation of 2-methyl-2-butene? What is the major organic product that is obtained when benzene reacts with 1-chlorohexane and AlCl3?
Benzene reacts (1) with chlorine, to form (a) substitution products (one-half of the chlorine forms hydrogen chloride) such as chlorobenzene, C6H5Cl; dichlorobenzene, C6H4Cl2(1,4) and (1,2); trichlorobenzene, C6H3Cl3(1,2,4); tetrachlorobenzene (1,2,3,5); and (b) addition produc...
is used, with acceptor being toluene and acid catalyst AlCl3, in combination with HCl. Preferred reaction conditions are 3-6 mol acceptor to one mol ditertiary butyl compound, 2-5 mol % catalyst, 10-60 degrees C. Tert-butylated acceptor may be chlorinated using SO2Cl2 in presence of AlCl3...
