Annelation of ring-opened cyclopropenium ions to coordinated cyclooctatetraene, and the x-ray structure of [Fe(CO)3 {σ,η3-C8H9(C3Ph3)}]

The X-ray structure of [Fe(CO) 3 {σ,η 3 -C 8 H 9 (C 3 Ph 3 )}], prepared by hydride ion addition to the product of the reaction between [Fe(CO) 3 (η 4 -COT)] (COT = cyclooctatetraene) and [C 3 Ph 3 ] + , reveals annelation of the ring opened cyclopropenium ion to the coordinated polyolefin.
