scheme or table, p. 6579 - 6584 (2009/04/06)
Lewis acidic nature of boron trichloride (BCl3) to coordinate to the carbonyl functionality was exploited for the synthesis of benzofurans via dehydrative cyclization. This mild and efficient procedure allowed for facile access to a number of h

A palladium(II)-catalyzed intramolecular addition of arylboronic acids to ketones was developed. Compared to Pd(OAc)2 catalysis system, cationic palladium complex with dppp as the ligand has higher catalytic activity and efficiency for wider sc
Halogen-metal exchange/cyclization of iodoketones: A direct synthesis of 3-arylbenzofurans
Kraus, George A.,Schroeder, Jacob D.
, p. 2504 - 2506 (2007/10/03)
The first synthesis of benzofuran 2 was achieved in 17% overall yield in seven steps. The key step was a halogen-metal exchange/cyclization reaction. Several examples of this reaction were reported. Georg Thieme Verlag Stuttgart.
Photochemistry of Vinyl Halides. Formation of Benzofurans by Photolysis of β-(o-Methoxyphenyl)vinyl Bromides
Suzuki, Tatsuo,Kitamura, Tsugio,Sonoda, Taka-aki,Kobayashi, Shinjiro,Taniguchi, Hiroshi
, p. 5324 - 5328 (2007/10/02)
Photolysis of β,β-bis(o-methoxyphenyl)-substituted vinyl bromides gave benzofuran derivatives which are derived from an intramolecular nucleophilic attack of the methoxyl group on an intermediate vinyl cation.With α-aryl-substituted vinyl bromides, only o
