A straightforward KHMDS mediated synthetic route to 9-arylfluorenes from readily available starting materials has been developed. This reaction involves S_NAr reactions of dioxide with arylacetonitriles, followed by decyanation reaction. The proposed transformation can also be used to furnish a densely arylated indene.

KHMDS介导串联S _N Ar脱氰基芳基化反应由二苯并噻吩二氧化物和芳基乙腈合成9-芳基芴

已经开发了一种简单的由KHMDS介导的从容易获得的起始原料合成9-芳基芴的合成路线。该反应包括小号_Ñ二氧化arylacetonitriles的氩反应，随后脱氰反应。所提出的转化也可以用于提供致密的芳基化的茚。
