Abstract
Abstract As part of our studies into the synthesis of polydentate phosphine-containing ligands, we have investigated the preparation of the phosphines (4; X[dbnd]O) and (4; X[dbnd]S). These are of interest both as potential dianionic bidentate ligands and as useful precursors of more complex polydentate ligand systems. A synthesis of the thiol system (4; X[dbnd]S) from 1,2-dinitrobenzene has been previously reported [1], but the observation [2], that 2-bromoaryl esters of phosphoric acid rearrange to give esters of arylphosphonic acids in the presence of alkyl lithiums, led us to consider whether a similar type of rearrangement might provide a convenient approach to both (4; X[dbnd]S) and (4; X[dbnd]O).
