The reaction of C5H5Rh(PMe3)C2H4 or C5H5Rh(PMe3)CO with CH2I2 affords the compound C5H5RhCH2I(PMe3)I from which stable cationic ylide-rhodium complexes X (L = PPh3, PPr3i, AsPh3, SMe2, NEt3; X = I, PF6) are prepared.In the pr

C5H5Rh(C2H4)PMe3 (1) reacts with CH2I2, CH2Br2, CH2ICl, and CH2ICN to yield the carbeoidrhodium(III) compounds (2-5).From 1 and CHX3 (X = Br, I) the complexes (6, 7) are obtained.The reactions of (2) with NaOCH3, NaSR (R = CH3, C6H5), KSCN and Na (Red-al) lead to the compounds (9), (11, 12), (13), and (14).With NaOH in C6H6/H2O in presence of a phase-transfer catalyst isomerization of 2 to give (10) occurs.Substitution of the carbon-bonded iodide in 2 by PPh3, PiPr3, NEt3, pyridine, AsPh3, SMe2, and tetrahydrothiophene gives the complexes X (15-21) in which the ylides CH2PPh3, CH2PiPr3, CH2NEt3, CH2NC5H5, CH2AsPh3, CH2SMe2, and CH2SC4H8 are formed as ligands.The crystal structure of 18 (L = NC5H5) has been determined.The result shows that the rhodium is octahedrally coordinated and that the Rh-C and C-N distances in the RhCH2NC5H5 group correspond to single bond lengths.The Rh-C(C5H5) distances vary between 217 (2) and 224 (3) pm thus reflecting the different trans influence of the ligands I, PMe3, and CH2NC5H5.
