Synthesis and characterization of substituted-allyl-rhodium complexes incorporating bidentate phosphine and phosphinite ligands

The reaction of (1,5-cyclooctadiene)(2-methylallyl)rhodium(I), [η3-(2-Me-C3H4)Rh(COD)], with chelating phosphines and phosphinites results in the smooth displacement of 1,5-cyclooctadiene and the formation of the new (2-methylallyl)rhodium complexes [η3-(2-Me-C3H4)RhL2], where L2 = Me2PCH2CH2PMe2, (p-Me-C6H4)2PCH2CH 2P(C6H4-p-Me)2, Ph2PCH2CH2CH2PPh2, cis-Ph2PCH=CHPPh2, (S,S)-Ph2PCH(CH3)CH(CH3)PPh2, HN(SiMe2CH2PPh2)2, Ph2PCH2CH2AsPh2, and (MeO)2PCH2CH2P(OMe)2, in good yields. Similarly, the reaction of a number of the above chelating ligands with the pure syn isomer of (1,5-cyclooctadiene)(1-methylallyl)rhodium(I), [η3-(1-Me-C3H4)Rh(COD)], results in a mixture of the corresponding syn and anti isomers with the syn form predominating. The preparation and spectral characterization of all new compounds are presented together with a discussion of the stereoselectivity of the substitution process.
