- Abstract
- A series of O-aryloximes I have been prepd. from tricarbonylchromium-complexed haloarenes II and ketoximes under
mild conditions. I underwent decomplexation in the presence of iodine and further cyclized in the presence of H2SO4 to
give benzofuran derivs. E.g. II (R1 = H, X = Cl) reacted with R2CR3:NOH (R2 = R3 = Me) to give I (same R1, R2, R3).
Sequential treatment of I with iodine followed by 98% H2SO4 gave benzofuran III. (literal)
