(Chemical Equation Presented) We herein report the development of one-pot procedures for the conversion of allyl aryl ethers to 2-methylbenzofurans (via sequential Claisen rearrangement and oxidative cyclization) and for the conversion of aryl homoallyl e
Cesium Fluoride-Mediated Claisen Rearrangements of Phenyl Propargyl Ethers: Effect of a Substituent on the Phenyl Ring on the Rearrangement

, p. 371 - 380 (2007/10/02)
Methoxy or methoxycarbonyl-substituted phenyl propargyl ethers were subjected to Claisen rearrangement either in the absence or in the presence of CsF.Substituent effect on the cyclization is discussed.
Nucleophilic Aromatic Substitution on Tricarbonylchromium-complexed Haloarenes: Synthesis of O-Aryloximes and Their Cyclization to Benzofurans

, p. 192 - 196 (2007/10/02)
A series of O-aryloximes have been prepared from tricarbonylchromium-complexed haloarenes in mild conditions.Title compounds are starting materials for benzofuran synthesis.
Aromatic Nucleophilic Substitution on Cr(CO)3-Complexed Halogenoarenes: A New Synthesis of O-Aryloximes and Their Cyclization to Benzofurans
Alemagna, Andreina,Baldoli, Clara,Buttero, Paola Del,Licandro, Emanuela,Maiorana, Stefano
, p. 417 - 418 (2007/10/02)
O-Aryloximes are synthesized by reaction of acetone oxime with Cr(CO)3-complexed halogenoarenes and then cyclized to give benzofurans.
