Calixarene-Based Copper(I) Complexes as Models for Monocopper Sites in Enzymes

A cavity that acts as a molecular funnel is formed from calix[6]arene 1 and [CuI(NCCH3)4]PF6 [Eq. (a)]. An exchange of the well‐protected acetonitrile ligand for other nitriles RCN is only possible with small R groups. The protection of the copper ions precludes oxidative dimerization; thus, the com...

Description
Summary:A cavity that acts as a molecular funnel is formed from calix[6]arene 1 and [CuI(NCCH3)4]PF6 [Eq. (a)]. An exchange of the well‐protected acetonitrile ligand for other nitriles RCN is only possible with small R groups. The protection of the copper ions precludes oxidative dimerization; thus, the complexes mimic the mononuclear site of copper enzymes.
