Abstract

The first examples of an optically active Birch reduced tertiary phosphine, viz. (RP)-(cyclohexa-2,5-dienyl)(3-pentyl)phenylphosphine, and successful hydrophosphination of the related racemic ligand (±)-(cyclohexa-2,5-dienyl)(2-propyl)phenylphosphine with PHPh2 in the presence of KOBut in thf to give a 1,2-cyclohexenebis(tertiary phosphine), viz. (±)-1,2-C6H8(PPh2)(PPhPri), are described; as confirmed by crystal structure determinations of [SP-4-4-(SP,S)]-chloro[(cyclohexa-2,5-dienyl)(3-pentyl)phenylphosphine][2-{1-(dimethylamino)ethyl}phenyl-C,N]palladium(II) and [SP-4-3-(±)]-dimethyl[(1-diphenylphosphino)(2-isopropylphenylphosphino)cyclohexene]platinum(II).
