Abstract

The dynamic photoluminescence properties, and potential quenching mechanisms, of anti-B18H22, 4,4′-Br2-anti-B18H20, and 4,4′-I2-anti-B18H20 are investigated in solution and polymer films.

Abstract

We report the synthesis and characterization of a 2D coordination polymer composed of a dianionic perhydroxylated boron cluster, [B12(OH)122−], coordinated to Zn(ii)—the first example of a transition metal-coordinated [B12(OH)12]2− compound.

Abstract

We report the synthesis of air-stable Pd(I) dimer complexes featuring biaryl phosphine ligands. Catalytic experiments suggest that these complexes are comptent precatalysts that can mediate cross-coupling amination reactions between aryl halide electrophiles with both aliphatic and aromatic amine nucleophiles. This work represents an expansion of the air-stable precatalyst toolbox for Pd-catalyzed cross-coupling transformations.
