| Abstract
| - Mechanistic studies on the ring-opening isomerization of methylenecyclopropanes into 1,3-dienes were carried out by use of hydrido−rhodium and −iridium complexes; X-ray structures of the intermediates of the reactions and their chemical properties have been obtained.
- 2-Phenyl-1-methylenecyclopropane and 2,2-diphenyl-1-methylenecyclopropane react with MH(CO)(PPh3)3 (M = Rh, Ir) to produce 1,3-dienes or theintermediate Rh and Ir complexes having a 3-butenylligand, depending on the conditions. The structures andchemical properties of the obtained complexes suggestplausible pathways for the ring-opening isomerizationof the methylenecyclopropanes to the correspondingdienes.
