Triphenylphosphine [...]link iridium hydrogen adduct and its preparation and use

The invention discloses a benzo-quinoline triphenylphosphine ring iridium hydride adduct. The compound has the general formula in the specification, wherein R is H,-CH3,-OCH3,-C6H5 or-CHO, and R is positioned in the position of 3, 5, 6 or 8 of benzo-quinoline. The preparation steps of the compound are as follows: taking a benzo-quinoline derivative, iridium trichloride and triphenylphosphine, adding into a solvent, performing heating reflux under gas protection, and filtering after the end of the reaction to obtain the benzo-quinoline triphenylphosphine ring iridium hydride adduct. The prepared benzo-quinoline triphenylphosphine ring iridium hydride adduct is a high-activity catalyst which can catalyze the reaction of aryl alkyne and aryl benzyl alcohol to obtain an aryl ketone compound. The benzo-quinoline triphenylphosphine ring iridium hydride adduct is taken as a metal catalyst, the using quantity of the catalyst is small, a cheap weak base is used, and then the reaction of the aryl alkyne and the aryl benzyl alcohol can be catalyzed efficiently. The method has the advantages of mild reaction conditions, wide range of reaction substrates, economy, high efficiency and the like, and further has important application values.

Facile tuning of the aggregation-induced emission wavelength in a common framework of a cyclometalated iridium(III) complex: Micellar encapsulated probe in cellular imaging

A simple synthetic protocol involving two steps was developed for the syntheses of a series of monocyclometalated iridium(iii) complexes. Initially, an intermediate, [IrHCl[(o-C6H3X)P(Ar) x-(PArxRy)2] [A (i, j, k, l)], six-coordinated iridium(iii) complex involving a 4-membered chelate was isolated. Then, it was transformed into a monocyclometalated iridium(iii) complex, [(C^N)Ir(PArx-1Ry)2(Cl(H)] (1-12), by the replacement of the 4-membered chelates with 5-membered cyclometalates. The intermediates and the complexes were structurally characterized by FTIR, 1H, 13C and 31P NMR spectroscopies. Octahedral coordination for Ir(iii) in 2, 8 and 9 was established by single crystal X-ray diffraction. Photo-physical experiments and quantum chemical calculations revealed a mixed LC/MLCT/LLCT nature for the lowest excited states of all these complexes that emit bright light in the solid state. Fine tuning of the emission wavelength throughout the visible range was achieved by suitable combinations of chromophoric cyclometalates and non-chromophoric aryl phosphine ligands. More interestingly, all the studied complexes were found to be aggregation-induced emission (AIE) active. One of these AIE active materials (6) was encapsulated inside polymeric micelles that inhibit the macroscopic precipitation of the aggregated complex, a strong emission. These colloidal luminescent particles were used as a potential non-toxic bio-imaging probe. This journal is the Partner Organisations 2014.

One-pot synthesis of ferrocenyl ketones containing biaryls and 6-aryl-2-ferrocenylquinolines via Ir/pd-cocatalyzed α-alkylation/suzuki reaction

An efficient PPh3-cyclometalated iridium(III) benzo[h]quinoline hydride 1/Pd(OAc)2-cocatalyzed three-component α-alkylation/ Suzuki reaction has been developed. The three-component reaction of 4-bromobenzyl alcohol, acetylferrocene, and arylboronic acids gives ferrocenyl ketones containing biaryls in moderate to good yields. This method was successfully applied to a one-pot synthesis of 6-aryl-2-ferrocenyl quinolines, using (2-amino-5-bromophenyl)methanol instead of 4-bromobenzyl alcohol.
