(7), which is also obtained by the thermal rearrangement of the isomeric alkyne derivative trans-[RhCl(HCCCO2Et)(PiPr3)2] (9). The reaction of 4 with methyl iodide unexpectedly gives the allene rhodium complex trans-[RhCl(η2-CH2=CCHCO2Et)(PiPr3)2] (10), whereas treatment of 6 with CH3I gives the alkyne compound trans-[RhCl(CH3CCC6H5)(PiPr3)2] (11).
