Bis-aminocyclopropenylidene carbene borane catalyzed imine hydrogenation

Certain borenium cations supported by carbenes can function as hydrogenation catalysts for imines. While many carbenes have been explored, variation of the other groups on boron has been less common. We have investigated several carbene-borane adducts in an attempt to understand the ability of a bis-amino cyclopropenylidene (BAC) carbene dicyclohexylborane adduct to hydrogenate relatively sterically unhindered benzyl imines. As an additional variant, a BAC carbene adduct of diphenylborane was prepared. A convenient preparation of diphenylboron fluoride via a potassium fluoroborinate salt was employed in this chemistry. Reaction of diphenylboron fluoride with a BAC carbene afforded a modest yield of a carbene-fluoroborane adduct. Reaction between the fluoroborinate salt and a lithium tetrafluoroborate adduct of the carbene provided the adduct in much improved yield and cleanliness, and the product was structurally characterized. The fluoroborate could be converted to a boron hydride through fluoride-hydride exchange with dimethylchlorosilane. The boron hydride adduct was also structurally characterized. Unlike the BAC carbene dicyclohexylborane adduct, the BAC carbene diphenylborane adduct showed essentially no activity in hydrogenation of imines or enamines.

Compound and organic luminescence display device

The invention relates to the technical field of organic electroluminescent materials, in particular to a compound and an organic luminescence display device. The compound has a structure shown by formula (I) in the description, wherein D represents an electron donor unit; A represents an electron receiver unit; m and n are respectively and independently selected from 1, 2 or 3; in addition, the sum of the m and the n is smaller than or equal to 4. When the compound is used as a luminous material, an object material or a main body material of the organic luminescence display device, high luminescence efficiency can be realized.

O,N-Chelated boron aminophenolate complexes. Crystal structure of BPh2(OC6H4(CH2NMe2)-2)

Two diphenylboron ortho-aminophenolate complexes, [BPh2(OC6H4(CH2NMe2)-2)] (2) and [BPh2(OC6H2(CH2NMe 2)2-2,6-Me-4)] (6), have been prepared in a

A Spectroscopic study of phenylboron halides

Phenylfluoroboranes have been prepared by the fluorination ofthe corresponding bromides with titanium tetrafluoride. The infrared spectra of the phenylhaloboranes, R3-nBXn (RC6H5, XF, Cl, Br, I), have been recorded in the 4000-4250 cm-1 region; an assignment of the fundamentals is suggested and characteristic frequency trends are discussed. An evaluation of the spectral data suggests that the structure of phenylfluoroboranes is distinctly different from that of the other halides in the series.
