摘要

据报道,一种芳基化策略可将 2-((二苯氧基磷酰)氧基)-2-芳基乙酸烷基酯转化为 α,α-二酯。当起始有机磷酸盐的芳基环上不带对位烷氧基时,TfOH 可以促进这种转化,但当存在这种基团时,则不需要任何添加剂。这些 2-((二苯氧基磷酰)氧基)-2-芳基乙酸烷基酯很容易从磷酸二苯酯插入芳基重氮乙酸酯中获得。

Friedel–Crafts-Type Arylation Strategy for the Conversion of Alkyl 2-((Diphenoxyphosphoryl)oxy)-2-arylacetates to α,α-Diaryl Esters

Friedel–Crafts-Type Arylation Strategy for the Conversion of Alkyl 2-((Diphenoxyphosphoryl)oxy)-2-arylacetates to α,α-Diaryl Esters

Friedel–Crafts-Type Arylation Strategy for the Conversion of Alkyl 2-((Diphenoxyphosphoryl)oxy)-2-arylacetates to α,α-Diaryl Esters

An arylation strategy allowing the conversion of alkyl 2-((diphenoxyphosphoryl)oxy)-2-arylacetates to α,α-diaryl esters is reported. This transformation can be promoted by TfOH when the starting organic phosphates do not carry para-alkoxy groups on their aryl rings, but it does not require any additives when such groups are present. These alkyl 2-((diphenoxyphosphoryl)oxy)-2-arylacetates can be readily accessed from the insertion of diphenyl phosphate into aryldiazoacetates.
