A process for preparing an allyl ether including reacting (a) a phenolic compound with (b) an allyl carboxylate or an allyl carbonate in the presence of (c) a transition metal or rare earth metal catalyst complexed with at least one strongly bonded, non-replaceable stable ligand whereby an allyl ether is formed. The ligand of the transition metal or rare earth metal catalyst complex may be (i) an olefinic-containing ligand or aromatic-containing ligand; or (ii) a polymeric ligand or a heteroatom-containing multidentate ligand.
Friedel–Crafts hydroxyalkylation through activation of a carbonyl group using AlBr3: an easy access to pyridyl aryl/heteroaryl carbinols
Aromatic electrophilic substitution of aromatic/electron rich heteroaromatic compounds with AlBr3 activated aldehydes/ketone to afford pyridyl aryl/heteroaryl or diaryl carbinols is described. The strong electron donating group dictates the regiochemical outcome of the product.
