New allylation and acylmethylation of aromatic compounds

Abstract

New direct allylation and acylmethylation of the aromatic compounds have been developed. A combination of allyltrimethylsilane and iodosoben zene gave rise to an allyl cationic species which was allowed to react with an aromatic compounds, a nucleophile, to give allylation products in good yields. Titanium(IV) chloride catalized addition of aromatic compounds to -nitro olefins afforded -aromatic nitronates which on treatment with acid in situ generated from titanium(IV) and water are smoothly converted to acylmethylated aromatic compounds in good yields.
