The first phosphorus-containing 11-membered ring: Reaction of the transient phosphinidene complex [MePW(CO)5] with 1,6-methanoannulene results remarkably in the sole formation of the stable CC insertion products 1 a (shown here) and 1 b, which have the first phosphorus-containing 11-membered ring. Characterization by X-ray crystallography and NMR spectroscopy was complimented with density functional calculations.
