Back Cover: Chiral Self‐Recognition between Stereogenic Tetrapalladium Units Affording Pd₈ Chains Supported by Homochiral Tetraphosphines (Chem. Eur. J. 3/2017)

Abstract

Chiral self‐recognition between stereogenic tetrapalladium units, [Pd4(rac‐dpmppm)2]2+ ((RR)2, (SS)2) and [Pd4(meso‐dpmppm)2]2+ ((RS)2) {dpmppm=[(Ph2PCH2)PhP]2CH2}, afforded Pd8 chains supported by homochiral dpmppm ligands, [Pd8(rac‐dpmppm)4]4+ ((RR)4, (SS)4) and [Pd8(meso‐dpmppm)4]4+ ((RS)2(SR)2, (SR)2(RS)2). Among ten possible stereoisomers, only four Pd8 chains were thermodynamically self‐aligned; the C2 chiral structure of the chain is determined by the configuration of the P centers inside.
