'Propylene spaced' allyl tin reagents: A new class of fluorous tin reagents for allylations under radical and metal-catalyzed conditions

Article abstract of DOI:10.1016/S0960-894X(98)00435-1

A new generation of propylene-spaced fluorous allyltin reagents [(Rf(CH₂)₃)₃SnCH₂CH=CH₂] is described. These succeed in radical allylations where their lower homologs (ethylene-spaced) fail, and they provide improved performance in transition metal catalyzed allylations. The reagents and byproducts are readily separated by simple fluorous-organic liquid-liquid or solid-liquid extractions.
