摘要：

Photolysis of [Fe(eta(5)-C(5)Me(5))(CO)(2)(C=CPh)] with methyl propynoate which bears a coordinating substituent (CO(2)Me) affords a metallabicyclic compound incorporating two molecules of the alkyne, whereas the reaction with alk-1-ynes (RC=CH) bearing a non-coordinating substituent (R=alkyl, Ph, SiMe(3)) produces paramagnetic 17e iron(I)-cyclopentadienone complexes [Fe(eta(5)-C(5)Me(5))(eta(4)-C(5)Me(5))(eta(4)-2-Ph-5-R-C5H2O)].
