- A twin-sulfur [...]/aryl heterocyclic compound phosphoric acid as the auxiliary ligand iridium complex of (by machine translation)
-
The invention relates to a nitrogen heterocyclic main ligand, in order to double-sulfur [...]/aryl heterocyclic phosphate compound as auxiliary ligand new iridium complex. Iridium complex molecular nitrogen heterocyclic and sulfur group contribute to improving the material of the electron mobility and control light-emitting color, so as to balance the cavity with electronic injection and transmission, widen the carrier composite area, promote the device efficiency, reduce efficiency roll-off. The invention the iridium complex synthetic simple, stable chemical property, easy to sublimation purification, device performance, in order to obtain high efficiency of the organic electroluminescent device and its application in the field of lighting and display provides the convenience.

- On the reaction of bis(phosphothioyl)disulfanes with hydroxamic acids, part I: Ionic versus radical reaction pathways
-
Among sodium N-alkyl-4-chlorobenzohydroxamates treated with bis(phosphothioyl)disulfanes >P(S)SSP(S)P(S) is phosphorothioyl, phosphonothioyl, and phosphinothioyl), only the N-methyl one yields quantitatively the respective O-phosphothioyl derivatives exhibiting complete inversion of configuration at phosphorus in a reaction whose products are inert toward dithiophosphate arising in the reaction. For branched N-alkyl benzohydroxamates, products of a SET process predominated. The mechanism of the title reaction is discussed.

- ZUR KENNTNIS DES NATRIUMDIPHENYLPHOSPHINOFORMIATS Ph2PCOONa
-
Ph2PCOONa 2, prepared from Ph2PNa and CO2, is readily hydrolyzed in protic media with formation of Ph2PH and CO2.Hydrolysis is much slower in NaOH and small quantities of Ph2P(O)O- and HCOO- are additionally formed.Reactions of 2 with RI in stoichiometrical amounts gave tertiary phosphines Ph2PR (R=Me, Et) while the phosphonium compound I resulted from 2 and MeI in excess.Ph2PCOOMe, Ph2PCOOSiMe3 or Ph2PCSSNa were obtained from 2 and (MeO)2SO2, Me3SiCl or CS2.Ph2P(O)ONa and Ph2P(S)SNa were isolated when 2 was reacted with O2 or S8 in benzene.

- Preparation and Some Reactions of Thioacyl Diphenylthiophosphinoyl and Thioacyl Diphenylphosphino Sulfides
-
The reaction of sodium or caesium dithiocarboxylates with diphenylthiophosphinic and diphenylselenophosphinic chlorides gives purple thioacyl diphenylthiophosphinoyl 5 and dark green thioacyl diphenylselenophosphinoyl sulfides 6, which are useful thioacylating reagents under mild reaction conditions.Thioacyl diphenylphosphino sulfides 22, which can be obtained by the similar method using diphenylphosphinous chlorides, react with methanol to yield the corresponding methyl dithiocarboxylates 15, while the reactions of 22 with N-chlorosuccinimide lead to hitherto unknown N-(thioacetylthio)succinimides 28.
