A general new haloalkylation method has been found in the boron halide catalyzed alkylation of benzene (and other aromatics) with fluorohaloalkanes. The C-F bond reacts preferentially over the C-Cl, C-Br, or C-I bonds, allowing the chloro-, bromo-, and iodoalkylations to proceed in ...
The Friedel-Crafts alkylation reaction of benzene is illustrated below. A Lewis acid catalyst such as FeCl3or AlCl3is employed in this reaction in order to form a carbocation by facilitating the removal of the halide. The resulting carbocation undergoes a rearrangement before proceeding with the alky...
The Friedel–Crafts reaction is one of the most important reactions in organic chemistry (Clark, 1994). The newer type of metal ion-exchanged Mt, MCl2-Mn +-Mt (M = Ni, Cu, Zn; n = 2) catalysed the benzylation of benzene (Scheme 9.3) efficiently (conversion 97%). The activity of ...
A simple and convenient methodology for the stereoselective construction of 2-benzyl substituted trisubstituted olefins via sulfuric acid catalyzed Fredel-Crafts reaction of benzene with Baylis-Hillman adducts is described.doi:10.1016/S0040-4039(97)00266-9Deevi Basavaiah...
A simple and efficient method for the synthesis of 1,1-diarylalkanes via the Friedel–Crafts-type alkylation reaction of electron-rich arenes with cinnamic acid ester derivatives or chalcones is reported. Iron triflate has been found to be the best catalyst for the Friedel–Crafts-type alkylation...
