Method for preparing benzodinitrogen compound by using gold complex

The invention relates to a method for preparing a benzodinitrogen compound by using a gold complex, which comprises the following step of: reacting an o-phenylenediamine compound and alkyne as raw materials with a gold complex containing a diphosphine ort

GOLD(I) COMPLEXES OF 1,2-DITERTIARY PHOSPHINO-O-CARBORANE LIGANDS: TWO-, THREE-, AND FOUR-CO-ORDINATION

Ditertiary phosphines (L) of the type R2P(C2B10H10)PR'2 (R = R, = Ph; R = R' = NMe2; R = Ph, R' = NMe2) react with tetraethylammonium dibromoaurate(I) to form three-co-ordinate complexes , which have been isolated and characterized by elemental analyses, and i.r. and 31P- n.m.r. spectroscopy.A dimeric two-co-ordinate complex, >, has also been isolated and characterized.The 31P- n.m.r. spectra of CD3COCD3-CH2Cl2 (1:1) solutions of L and - show evidence for the formation of dimeric two-co-ordinate , dimeric three-co-ordinate , monomeric three-co-ordinate , and four-co-ordinate Br complexes.The unusual four-co-ordinate mixed-ligand complex ->Br is also observed.Phosphorus-phosphorus coupling constants decrease from three-co-ordinate to four-co-ordinate gold(I) complexes, as expected.The tertiary phosphine H(C2B10H10)PPh2 also gives > two-co-ordinate complexes.
