摘要：

Gamma-Benchrotrenic pyrylium salts synthesis is reported. N.M.R. data and theoretical calculations suggest that the Cr(CO)3 fragment is electron donating towards the pyrylium ring. X-ray structure of the complexe pyrylium salt indicates that the electron transfer does not implicate the chromium d orbitals.
