Tripod Ligands with Three Different Donor Groups: Synthesis and Coordination of CH3C(CH2PR2)(CH2PR'2)(CH2PR"2)

Tripod ligands CH3C(CH2PR2)(CH2PR'2)(CH2PR"2), 6(a-e), with three different donor groups are obtained from CH3C(CH2Cl)(CH2Br)(CH2OSO2CF3), 3, by successive replacement of the three different leaving groups. 3 itself is easily accessible from CH3C(CH2OH)3 in a few simple steps.The general applicability of this strategy is demonstrated by the preparation of five different ligands 6(a-e).For one specific example (6a) the coordination behavior is exemplified by the synthesis of its Mo(CO)3 derivative: CH3C(CH2P(Ph)2)(CH2P(3-Tol)2)(CH2P(4-Tol)2)*Mo(CO)3 (7).All compounds, including their intermediates CH3C(CH2Cl)(CH2Br)(CH2PR2), 4(a-c), and CH3C(CH2PR2)(CH2PR'2)(CH2Cl), 5(a-c), have been obtained in an analytically pure state and fully characterized by their spectroscopic data.The methods developed lend themselves to the almost deliberate shaping of tripod metal templates.Key words: Chiral Tripod Ligands, Chiral Tripod-Molybdenum Complexes, Synthesis, Chiral Triphosphines, Functionalized Neopentyl Compounds
