Chizhov,Slepukhin,Ovchinnikova,Fedorova,Rusinov,Filyakova,Charushin
experimental part, p. 2122 - 2125 (2011/06/26)
O-Alkylation of 2-acetylphenols with α,ω-dichloro derivatives of oligoethylene glycols in the presence of KOH and Al2O3 in DMF gave the corresponding podands. Their condensation with ethyl trifluoroacetate afforded fluorine-containin

, p. 1627 - 1634 (2007/10/02)
Low-valent titanium-induced reductive coupling has been used to prepare stilbene cycles.Bis(carbonyl) ethers, 1h-3h and 1m-3m, have been prepared from the reactions of salicylaldehyde (h) and 2-hydroxyacetophenone (m) with diethylene glycol ditosylate (1)
