  Synthesis of Substituted Benzenes via Bi(OTf)₃-Mediated Intramolecular Carbonyl Allylation of α-Prenyl or α-Geranyl β-Arylketosulfones

  摘要：

  Intramolecular carbonyl allylation of alpha-prenyl or alpha-geranyl beta-arylketosulfones 5 in the presence of molecule sieves (MS) affords substituted benzenes 6-7 in moderate to good yields. The facile transformation proceeds by a synthetic sequence starting with the alpha-prenylation or alpha-geranylation of 1 and the Bi(OTf)(3)-mediated annulation of 5 followed by a sequential desulfonative aromatization or then an intramolecular FriedelCrafts alkylation. A plausible mechanism has been studied and proposed.

  An imidazolium chloride tagged palladium(II) complex has been conveniently prepared and structurally analyzed. It is active toward cross-coupling of arylboronic acid with aryl halide and benzoyl chloride, giving moderate to high yield of the desired biaryls and aryl ketones, respectively. The present phosphine-free (N–N)Pd(II) complex could be efficiently recycled at least four times with minor decrease

  Swapped: Commercially available quinolinone derivatives (1 or 2, see scheme) were reacted with arylboronic acids in the presence of a RhI complex to give aryl(quinolin‐8‐yl)methanone products 3 in medium to good yields. A mechanism that involves the in situ oxidation of RhI to RhIII by O2 in the presence of CuI was proposed.

  The SUZUKI reaction of organoboron compounds with 4-[18F]fluoroiodobenzene has been developed as a novel radiolabelling technique in 18F chemistry. The cross-coupling reaction of p-tolylboronic acid with 4-[18F]fluoroiodobenzene was used to screen different palladium complexes, bases and solvents. Optimized reaction conditions (Pd2(dba)3, Cs2CO3, acetonitrile, 60°C for 5 min) were further applied to
