摘要:A single-step method of making tetradentate platinum complexes is disclosed. The method advantageously allows the formation of a platinum complex in a single step, even with sterically hindered ligands, without the use of highly reactive intermediates. The compounds made by the disclosed method are useful in OLED applications.

标 题 :One-step synthesis of aromatic organic diselenides
发明人：GRUSHKIN BERNARD; SALZMAN MICHAEL N
权利人:XEROX CORP
摘要:Disclosed is a novel method for the preparation of aromatic organic diselenide compounds. The method involves reacting an alkali metal diselenide with certain halogenated aromatic compounds in dimethylformamide to form the corresponding aromatic diselenide. The use of dimethylformamide enables one to prepare certain aromatic diselenide compounds containing two replaceable halogen atoms in a one-step process.
