Reaction of RPyI, CuI, and CuCN produces anionic iodocyanocuprate(i) chains, (RPy)2[Cu2I3CN] which exhibit charge transfer that is influenced by the hydrogen bonding between the cation and the triiodide groups.

AbstractAn asymmetric organocatalytic nucleophilic aromatic substitution reaction of azlactones with electron-deficient aryls was established. A variety of α-aryl α-alkyl α-amino acid esters and peptides were obtained in decent yields and stereoselectivities. A new bifunctional catalytic mode involving charge-transfer interaction and hydrogen bonding is proposed to explain the enantioselectivity.
