Photolysis of
[Fe(η5-C5Me5)(CO)2(C
CPh)] with methyl propynoate which bears a coordinating
substituent (CO2Me) 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, SiMe3) produces paramagnetic 17e
iron(I)-cyclopentadienone complexes
[Fe(η5-C5Me5)(η4-2-Ph
-5-R-C5H2O)].
