efficiently synthetized via diethylzinc-promoted Wittigreaction using a phosphonium-supported triphenylphosphine SCG–PPh31, which possesses similar reactivity as its parent analog triphenylphosphine. The main advantage of this system is the use of a novel low-molecular-weight support that is soluble in solvents of medium polarities for the attachment of reagents and insoluble in solvents of low polarities
