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.
描述了新一代的丙烯间隔氟烯丙基锡试剂[(Rf(CH2)3)3SnCH2CH = CH2]。这些在低级同系物(乙烯间隔的)失效的自由基烯丙基化中成功,并且在过渡金属催化的烯丙基化中提供了改进的性能。试剂和副产物可通过简单的氟有机液-液或固-液萃取轻松分离。
