Abstract: Quantum‐chemical calculations were used to describe both the acidity of aluminabenzene‐based Lewis acids and stability of aluminabenzene‐based anions. Aluminabenzene itself was found to exhibit greater acidity than antimony pentaflouride, and thus can be qualified as… read more here.

DOI: 10.1002/marc.201800456
Abstract: A new B-N functionalized polyaromatic building block for conjugated hybrid polymers is developed. Bromine-functionalized dipyridylfluorene is first subjected to Lewis-base-directed electrophilic borylation and subsequently incorporated into conjugated polymers via transition-metal-catalyzed cross-coupling reactions. The borane monomer… read more here.

Abstract: A novel synthesis of five-membered cyclic nitrones has been developed based on the Lewis acid-catalysed [3+2]-annulation reaction of D-A cyclopropanes with 1,4,2-dioxazoles. Broad substrate scope and generally good yield make this reaction useful in the… read more here.

DOI: 10.1039/c9cc04010b
Abstract: The P(iii) dication [(terpy)PPh]2+ is oxidized by reaction with o-chloranil or 9,10-phenanthrenequinone to give the P(v) dications [(terpy)(C6Cl4O2)PPh]2+ and [(terpy)(C14H8O2)PPh]2+, respectively. These species are coordinatively saturated at phosphorus and yet display the ability to effect… read more here.
