Vinylboronic esters and allylboronic esters are well known to afford olefins by protodeboronation, and therefore homoallenylboronic esters should be similarly available as precursors for 1,3-dienes, but this strategy has not been well explored due to

Linker structures were systematically investigated for use in designing halogen-bond donor catalysts with two-point activation modes based on perfluoroiodobenzenes. Tetrafluorophenylene, phenylene, and acetylene were examined as potential linkers, an

A quantitative approach for the development of halogen-bonding-driven anion-binding catalysts was studied using 4-substituted perfluorinated iodobenzene. 19 F NMR titrations were used to determine the binding constants K for chloride, and their catal
