The six-coordinated Cd 2+ ions in 3 are bridged by the acetylenedicarboxylato ligand to form 1D zigzag chains, which are interconnected by bpp ligands to construct 3D metal–organic framework with a (4 8 · 6 7) topology. The fluorescent spectra of 1– 3 indicate intraligand fluorescence...
The zirconocene complexes Cp2Zr(L)(2-Me3SiC2SiMe3) (1a: L = THF; 1b: L = pyridine) and the ethylene bis(tetrahydroindenyl) complex rac-(ebthi)Zr(2-Me3SiC2SiMe3) (2) react with 2,3,5,6-tetrafluoropyridine with C-H bond activation to produce the 4-substituted pyridyl complexes ...

were evaluated. We found that using 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (Sphos) as the ligand resulted in high yields with a low catalyst loading under milder reaction conditions (3aq–at). Furthermore, the electron-withdrawing internal alkyne dimethyl acetylenedicarboxylate as the subs...
