Abstract
The cationic diiron bridging methylidyne complex
[ (C5H5)(CO)FeI2(p-CO)(p-CH)'PF6(1-) is very electrophilic.'
Nucleophiles such as CO and NMe3 add to the
methylidyne carbon of 1 to form stable 1:l adducts.' The
reactions of alkenes with 1, which lead to either p-alkylidyne
or p-alkenyl products, are initiated by an interaction
of the alkene with the electrophilic methylidyne carbon.
For ethylene, monosubstituted alkenes, and isobutylene,
the transition state for reaction with 1 involves interaction
of the methylidyne carbon with the least substituted alkene
carbon and development of partial positive charge at the
more substituted alkene carbon.
