The rhodacycloheptane derivative 2 is easily prepared in good yields from tris(triphenylphosphane)rhodium chloride or carbonylbis(triphenylphosphane)rhodium chloride and 3,3-dimethylcyclopropene.Spectroscopic data and X-ray analysis show that 2 is monomeric and has a syn,anti,syn structure.The hydrocarbon group of 2 is eliminated by reaction of 2 with CO to give hexamethyl-tris-?-homobenzene (5) and hexamethyl-tris-?-homotropone (4) in a ratio of 1:4.The X-ray structure of 4 is also given.
