ABSTRACT
It is common knowledge [85, 87] that phenol alkenylation by alkenyl halides may be carried out in two directions: with formation of 0-or Calkenylation products and with respect to the reaction conditions. For example, as the reaction is performed in nonpolar solvents in the presence of potassium or sodium metal, C-alkenylation is the basic process carried out with low yield of alkenyl phenols, whereas in polar solvents in the presence of an alkaline agent (K2C03) 0-alkenylation dominates giving high yield of allyl phenol esters. Therefore, alkenyl aryl esters were synthesized according to the well-known technique [146] in polar solvents (acetone or acetonitrile) in the presence nonaqueous potassium carbonate. The initial substances were phenols (phenol, aand p-cresols, o-and p-chlorophenols, 2,4-dichlorophenols) and alkenyl chlorides (2,3-, l ,3-dichloro, 1 ,2,3-, 1,1 ,3-trichloro, 1,1 ,2,3-tetrachloro-, 2chloromethyl-3-chloro-, 2-methoxymethyl-3-chloro-1-propenes), a part of which was extracted from alkenyl chloride large-tonnage production wastes (2,3-, 1,3dichloro-and 2-chloromethyl-3-chloro-1-propenes).
