Construction and probing of multisite chiral catalysts: dendrimer fixation of c2-symmetrical diphosphinerhodium complexes.

Abstract

A series of chiral phosphine-functionalized poly(propyleneimine) (PPI) dendrimers was synthesized by the reaction of carboxyl-linked C(2)-chiral pyrphos ligand (pyrphos=3,4-bis(diphenylphosphino)pyrrolidine) with zeroth-fourth generation PPI using ethyl-N,N-dimethylaminopropylcarbodiimide (EDC)/1-hydroxybenzotriazol as a coupling reagent. The dendrimers… (More)
