PHOSPHEPINE MATRIX COMPOUND FOR A SEMICONDUCTING MATERIAL

The present invention is directed to a compound comprising at least one phosphepine ring and having the phosphorous atom of the phosphepine ring substituted with at least one monovalent substituent R, wherein (i) R is selected from aryls and heteroaryls c

Ortho-Trialkylstannyl Arylphosphanes by C-P and C-Sn Bond Formation in Arynes

A novel and efficient approach to ortho-trialkylstannyl arylphosphanes by the reaction of arynes generated in situ with stannylated phosphanes (R3Sn-PR2) is described. Concurrent C-P and C-Sn bond formation occurs with high yields, and stannylated products are easily transformed into valuable ortho-substituted arylphosphanes. The reaction features high efficiency, good regioselectivity, and excellent practicality.

NEAR INFRARED STRONGLY LUMINOUS RARE EARTH COMPLEX

The present invention has been created to provide a near infrared high emission rare-earth complex having an excellent light-emitting property in the near infrared region. The near infrared high emission rare-earth complex of the present invention is characterized in that its structure is expressed by the following general formula (1): where Ln(III) represents a trivalent rare-earth ion; n is an integer equal to or greater than three; Xs represent either the same member or different members selected from a hydrogen atom, a deuterium atom, halogen atoms, C1-C20 groups, hydroxyl groups, nitro groups, amino groups, sulfonyl groups, cyano groups, silyl groups, phosphonic groups, diazo groups and mercapto groups; and Z represents a bidentate ligand.

General synthetic route to chiral flexible biphenylphosphine ligands: The use of a chiral additive enables the preparation and observation of metal complexes incorporating the enantiopure form

equation presented The enantio-and diastereomerically pure metal complex of a chirally flexible BIPHEP ligand is obtained through enantiomer-selective coordination of a BIPHEP-Ru complex with enantiopure 3,3′-dimethyldiaminobinaphthyl, DM-DBN, followed by

2,2′-Bis(diphenylphosphino)biphenyl revisited

The reaction between 2,2′-dilithiobiphenyl and two equivalents of chlorodiphenylphosphine is confirmed to afford equal amounts of 9-phenyl-9-phosphafluorene (2) and triphenylphosphine. 2,2′-Bis(diphenylphosphino)biphenyl (1,1′-biphenyl-2,2′-diylbis(diphenylphosphine) (1)) can be conveniently prepared by Ullmann coupling of 2-iodophenyldiphenylphosphine oxide and subsequent reduction with trichlorosilane.
