Transition-metal-promoted ring-opening reactions of vinylcyclopropenes. 1,2,3,5-η-Penta-2,4-dienediyl and 1,5-η-penta-2,4-dienediyl (1-metallacyclohexa-2,4-diene) complexes of rhodium(III) and iridium(III) and their conversion to (η5-cyclopentadienyl)hydridometal compounds

1,2,3-Triphenyl-3-vinyl-1-cyclopropene (2) reacts with "MCI(PMe3)2" (M = Rh, Ir) to give novel complexes 3a,b containing the 1,2,3,5-η-penta-2,4-dienediyl ligand, one of which, the iridium species 3b, has been crystallographically characterized. In contrast, reaction of 2 with the bulkier reagent "RhCl(P-i-Pr3)2" yields directly the (cyclopentadienyl)hydridorhodium complex 6. Reaction of 3a with (acetylacetonato)thallium affords the (1,5-η-penta-2,4-dienediyl)rhodium (1-rhodacyclohexa-2,4-diene) complex 8 which has also been crystallographically characterized.
