Abstract
The first nine-membered triphosphorus macrocycles based on an o-benzobis(et hane-1,2-diyl) core have been prepared in high yield by the coupling of 1,2 -diphosphinobenzene with trivinylphosphine on a cationic (eta(5)-pentamethy lcylopentadienyl)iron(II) template. Hydrogenation of the vinyl function fol lowed by alkylation of the secondary phosphines gives the coordinated triet hyl macrocycle, which has been structurally characterized.
