The X-ray structure of [Fe(CO)3 σ,η3-C8H9(C3Ph3)}], prepared by hydride ion addition to the product of the reaction between [Fe(CO)3(η4-COT)] (COT = cyclooctatetraene) and [C3Ph3]+, reveals annelation of the ring opened cyclopropenium ion to the coordinated polyolefin.

The firstexample of the reactions of cyclopropenes with N-acyliminium cations is described. 3-(1H-Inden-3-yl)isoindolin-1-ones and cyclopropa[c]isoindolo[2,1-a]quinolones were prepared by BF3·OEt2 mediated reactions of cyclopropenes with the N-acyliminium cations, generated from 2-aryl(benzyl)-3-hydroxyisoindolin-1-ones.

in a molecule is reported. This method is based on the reaction of stable organic cations with a cycloheptatrienyl anion totally substituted with methoxycarbonyl groups. After the formation of a C–C bond between two different carbocycles, some further transformations take place to give cage structures.

the iridium tetracarbonylate [PPN][Ir(CO)4] (1a) with triphenylcyclopropenyl tetrafluoroborate [C3Ph3][BF4] afforded two dinuclear species Ir2(CO)4(μ,η1:η2-C3Ph3)(μ,η2:η3-C3Ph3) (2) and Ir2(CO)4(μ,η4:η4-C6Ph6) (3a) resulting from the ring opening and in the latter case, coupling of the resulting acyclic, propenyl ligands. The analogous reaction with [PPN][Rh(CO)4] (1b) afforded only the rhodium analogue
