Abstract:
Square-planar rhodium(I) complexes [RhCl(iPr 2 PC 2 H 4 Y) 2 ] (8, 9) containing one chelating and one P-bonded monodentate phosphine ligand are prepared from [RhCl(C 8 H 14 ) 2 ] 2 (7) and the new functionalized phosphines iPr 2 PC 2 H 4 Y (5,6). Reaction of 9 (Y = NMe 2 ) with CO and of 8 (Y = OMe) with CO, C 2 H 4 , C 2 H 2 , C 2 Ph 2 and HC 2 Ph leads to opening of the chelate ring and formation of the complexes trans-[RhCl(L)(η 1 -P–iPr 2 PC 2 H 4 Y) 2 ] (10-15). Treatment of 8 with H 2 gives the dihydridorhodium(III) compound [RhH 2 Cl(iPr 2 PC 2 H 4 OMe) 2 ] (16). The vinylidene complexes trans-[RhCl(=C=CHR)(η 1 -P– iPr 2 PC 2 H 4 OMe) 2 ] (17, 18) are obtained by thermal or pyridine promoted rearrangement of 13 (L = C 2 H 2 ) and 15 (L = HC 2 Ph). 13 and 15 have also been used as starting materials for the synthesis of the cyclopentadienyl alkyne and vinylidene complexes 19-21. The X-ray crystal structure of the parent compound 8 was determined.
