摘要：

Ferrocenyl and pyridyl methylenepyrans were obtained from a Wittig reaction between a pyran phosphorane and ferrocenyl or pyridyl-aldehydes. The nucleophilic nature of the exocyclic C-C bond allowed the formylation of these compounds by a Vilsmeier type reaction. All the new products were characterized by IR spectroscopy, H-1 and C-13 NMR spectroscopy, mass spectroscopy and (or) elemental analysis. Electrochemistry of representative compounds 2, 10 and 13 was undertaken. In addition, a crystal structure of the ferrocenylpyranylidene aldehyde 5 was described, and the pyrylium character of this compound was specified. (C) 2009 Elsevier B.V. All rights reserved.
