Polymerization of Ethylene with Cationic Palladium and Nickel Catalysts Containing Bulky Nonenolizable Imine−Phosphine Ligands
A number of bulky, nonenolizable Pd(II) and Ni(II) imine−phosphine complexes have been synthesized and tested in the ethylene polymerization. These catalysts show improved temperature stability with
Catalytic coupling of C-H and C-I bonds using pyridine as a directing group.
A method for the palladium-catalyzed arylation of pyridines and pyrazoles has been developed and a bromo substituent is tolerated on the aryl iodide coupling component.
Thermally robust and porous noncovalent organic framework with high affinity for fluorocarbons and CFCs.
A small organic molecule is reported that organizes into a noncovalent organic framework with large empty pores, stable to at least 250 °C and porous, with an accessible surface area of 1,159 m(2) g(-1).
Carbon-hydrogen bond functionalization approach for the synthesis of fluorenones and ortho-arylated benzonitriles.
A sequence consisting of palladium-catalyzed benzamide ortho-arylation/reaction with (CF3CO)2O was developed allowing a convenient one-pot synthesis of ortho-arylated benzonitriles and fluorenone
Phosphinidine-Palladium Complexes for the Polymerization and Oligomerization of Ethylene
Several cationic palladium complexes containing bulky phosphinidine-imine, phosphinidine-sulfide, and imine-sulfide ligands have been prepared. These complexes catalyze the oligomerization and
