  摘要：

  Diacetylation of benehrotrenic alkenes by acetic anhydride and weak Lewis acid (ZnCl(2), BF(3)-OEt(2)) is reported. A series of gamma-benchrotrenic pyrylium salts is obtained together with the mono and the diacetylated products. The first organometallic fused rings pyrylium sails are obtained. In connection with the electron donating effect of the Cr (CO)(3) group, the influence of rings deconjugation on NMR data is discussed. Finally the reaction of acyclic and cyclic gamma-benchrotrenic pyrylium salts with nucleophiles is described. (C) 1997 Elsevier Science S.A.

  摘要：

  A series of 2,6-dimethyl- or 2,6-diphenylpyrylium cations, [R'-C(5)H(2)R ''O-2](+), which bear organometallic substituents at the 4-position, have been synthesized. The molecules in which R' = (C6H5)Cr(CO)(3), R '' = Me, 1, R' = (C5H4)Mn(CO)(3), R '' = Ph, 8, R' = (C5H4)Fe(C5H5), R '' = Me, 9, and R' = (C5H4)Re(CO)(3), R '' = Ph, 10, have been identified spectroscopically, and the complexes 1 and 8 have also been characterized by X-ray crystallography as CrC16H13O4+ PF6- and MnC25H16O4+ BF4-, respectively. The pi-complexed ring bearing either a Cr(CO)(3) or a Mn(CO)(3) moiety is almost coplanar with the pyrylium ring, as are the phenyl rings in 8. The structural and spectroscopic data indicate that the delocalization of the positive charge on the pyrylium ring onto the metal is rather minimal. These pyrylium salts react readily with benzylamine, or with beta-alanine ethyl ester, to form the corresponding pyridinium salts. In particular, the ferrocenyl derivative, 9, yields a crystalline pyridinium salt, 15, with the ethyl ester of beta-alanine.
