Palladium(O)-catalyzed substitution of allylic substrates in an aqueous-organic medium
摘要:
A palladium(0)-water soluble catalyst prepared in situ from palladium acetate and the sulfonated triphenyl phosphine P(C6H4-m-SO3Na)(3) (or tppts) is an efficient catalyst for allylic substitution with various carbon and heteronucleophiles in an aqueous-organic medium, allowing a very easy separation of the product(s) and the recycling of the catalyst.
