Preparation method of 1-iododibenzofuran

The invention provides a preparation method of 1-iododibenzofuran. The preparation method comprises the following steps: adding potassium tert-butoxide, dimethyl ether and cuprous iodide into a firstreactor, stirring the mixture under the protection of nitrogen gas, adding m-dinitrobenzene dissolved with pyridine into a system, then dissolving potassium tert-butoxide and o-iodophenol with dimethyl ether, adding the dissolved mixture into the system, fully reacting under the protection of the nitrogen gas, and separating to obtain 1-nitryldibenzofuran; then adding 1-nitryldibenzofuran into a second reactor, adding ethanol, water, iron powder and ammonium chloride, fully reacting, and separating to obtain 1-aminodibenzofuran; adding the 1-aminodibenzofuran into a third reactor, then addinghydrochloric acid, dropwise adding a sodium nitrite solution and a KI solution, fully reacting, and separating to obtain 1-iododibenzofuran. The preparation method has the beneficial effects of avoidance of carrying out the reactions under an ultralow temperature reaction condition, simple and feasible synthetic method, stable productivity, higher yield and low pollution, and has remarkable advantages on the aspect of batch production.

Cu(II)-Mediated N-H and N-Alkyl Aryl Amination and Olefin Aziridination

Cu(II)-mediated direct NH2 and NH alkyl aryl aminations and olefin aziridinations are described. These room-temperature, one-pot, environmentally friendly procedures replace costly Rh2 catalysts and, in some instances, display important differences with comparable Rh2- and Fe-supported reactions.

PHOSPHORESCENT EMITTERS

Compounds including a ligand with a dibenzo-fused 5-membered ring substituent are provided. In particular, the compounds may be iridium complexes including imidazole coordinated to the dibenzo-substituted ligand. The dibenzo-fused 5-membered ring moiety of the ligand may be twisted or minimally twisted out of plane with respect to the rest of the ligand structure. The compound may be used in organic light emitting devices, particularly as emitting dopants in blue devices. Devices comprising the compounds may demonstrate improved stability while maintaining excellent color.

An aryl to imidoyl palladium migration process involving intramolecular C-H activation

Biologically interesting fluoren-9-one and xanthen-9-one derivatives have been prepared by a novel aryl to imidoyl palladium migration, followed by intramolecular arylation. The fluoren-9-one synthesis appears to involve both a palladium migration mechanism and a C-H activation process proceeding through an unprecedented organopalladium(IV) hydride intermediate. The results from deuterium labeling experiments are consistent with the proposed dual mechanism.

Preparation of esters of phosphorus acids

Esters of phosphorus acids are prepared by an improved process whereby aromatic alcohols and phosphorus halides are reacted at specified temperatures in the presence of amine catalysts thereby providing high yields of substantially pure esters and allowing preparation of selected halogen-containing mono- and di-esters of phosphorus acids wherein halogen is directly bonded to phosphorus having substantially no side reactant contamination. The phosphorus esters are useful as intermediates in the preparation of plasticizers, oil additives and functional fluids.
