Persulfonylation of Amines Applied to the Synthesis of Higher Generation Dendrimers.

[摘要]：Systematic anal. of the persulfonylation of branched arom. oligoamines with different arylsulfonyl chlorides allowed optimization of the repetitive steps involved in the synthesis of the sulfonimide-based dendrimers. The optimized procedures afforded the fourth generation N- and pentaphenylene-centered dendrimers with 16 and 32 peripheral groups, resp. Anal. of products of incomplete substitution showed that the amino groups in arom. oligoamines are persulfonylated consecutively.
