Regioselective synthesis of polysubstituted benzenes from Baylis-Hillman adducts via [4+2] annulation protocol

A new and regioselective [4+2] benzannulation protocol toward polysubstituted benzenes was developed. A nitroalkane derivative, which was prepared from Baylis-Hillman adduct, served as the four-carbon unit and a Michael acceptor as a two-carbon unit. Viny

Synthetic Methods and Reactions; 126. Trifluoromethanesulfonic Acid/Triethylsilane: A New Ionic Hydrogenation Reagent for the Reduction of Diaryl and Alkyl Aryl Ketones to Hydrocarbons

Benzophenones (except for 4,4'-dialkoxy- and sterically hindered derivatives), certain acetophenones, and 1-indanone can be reduced to the corresponding hydrocarbons in good yields by reaction with trifluoromethanesulfonic acid and triethylsilane.

SYNTHESIS OF SUBSTITUTED 2,4,5-TRIMETHYLDIPHENYLMETHANES

2,5-Dimethyldiphenylmethane and its 2'- and 4'-methyl, chloro, and nitro derivatives were obtained by the reaction of substituted benzyl chlorides with p-xylene in the presence of ferric chloride and zinc stearate.The yields of the 2,5-dimethyldiphenylmethanes depend on the nature of the substituent in the benzyl chloride and decrease with the substituents in the order NO2>Cl>H>CH3.The 2' and 4'-methyl, chloro, and aminoderivatives of 2,4,5-trimethyldiphenylmethane were synthesized by chloromethylation of the obtained diphenylmethanes with paraform in acetic acid in the presence of zinc chloride followed by reduction of the 2,5-dimethyl-4-chloromethyldiphenylmethanes with zinc in acetic acid.
