Additions of Lithiated β-Hydroxy Alkyldiphenylphosphine Oxides to Aldehydes, and Palladium(II)-catalysed Allylic Transpositions of Bis-acetoxy Alkyldiphenylphosphine Oxides: Synthesis of O-Protected (E,E)- and (E,Z)-Hepta-2,4-dien-1-ol and of Alkyldipheny

Saturated and unsaturated β- and δ-hydroxyalkyldiphenylphosphine oxides give adducts with aldehydes after treatment with an excess of butyllithium.Normal Horner-Wittig reactions lead to O-trityl (E,E)- and (E,Z)-hepta-2,4-dien-1-ols.Allylic rearrangement

Palladium(II)-catalysed rearrangement of allylic acetates 5, which contain a diphenylphosphinoyl group, yields transposed acetates 6 in good yield.The reaction is mild, general for most substitution patterns, and stereospecific.The transposed acetates 6 m
