A correction to the article "The Nucleophilicity of Persistent α-Monofluoromethide Anions," by Z. Zhang et al, published in a previous isssue is presented.

The precise control over hierarchical self‐assembly of superstructures relying on the elaboration of multiple noncovalent interactions between basic building blocks is both elusive and highly desirable. We herein report a terpyridine‐based metallo‐cage T with a tetrahedral motif and utilized it as an efficient building block for the controlled hierarchical self‐assembly of superstructures in response to different halide ions. Initially, the hierarchical superstructure of metallo‐cage T adopted a hexagonal close‐packed structure. By adding Cl−/Br− or I−, drastically different hierarchical superstructures with highly‐tight hexagonal packing or graphite‐like packing arrangements, respectively, have been achieved. These unusual halide‐ion‐triggered hierarchical structural changes resulted in quite distinct intermolecular channels, which provided new insights into the mechanism of three‐dimensional supramolecular aggregation and crystal growth based on macromolecular construction. In addition, the chiral induction of the metallo‐cage T can be realized with the addition of chiral anions, which stereoselectively generated either PPPP‐ or MMMM‐type enantiomers.

The trifluoromethanide anion is the postulated key intermediate in nucleophilic trifluoromethylation reactions. However, for more than six decades, the trifluoromethanide anion was widely believed to exist only as a short-lived transient species in the condensed phase. It has now been prepared in bulk for the first time in THF solution. The trifluoromethanide anion with the [K(18-crown-6)]+ cation was unequivocally characterized by low-temperature 19F and 13C NMR spectroscopy. Its intermediacy in nucleophilic trifluoromethylation reactions was directly evident by its reaction chemistry with various electrophilic substrates. Variable-temperature NMR spectroscopy, along with quantum mechanical calculations, support the persistence of the trifluoromethanide anion. [ABSTRACT FROM AUTHOR]
