In this study, we developed a simple transition-metal-free borylation reaction of aryl bromides. Bis-boronic acid (BBA), was used, and the borylation reaction was performed using a simple procedure at a mild temperature. Under mild conditions, aryl bromides were converted to arylboronic acids directly without any deprotection steps and purified by conversion to trifluoroborate salts. The functional group tolerance was considerably high. The mechanism study suggested that this borylation reaction proceeds via a radical pathway.

Organozinc pivalates, a recently developed air- and moisture-stable organozinc species, were found for the first time as excellent organometallic species in the monoorganylation of trialkyl borates whereby boronic acids were prepared in high yields. The significant advantage of organozinc pivalates over another previously employed organometallic reagents, e. g., organolithium reagents, Grignard reagents and organozinc halides, is that the generation of multiorganylation byproducts such as borinic acids and trialkylboranes were completely suppressed. Additionally, the in situ generated boronates could be directly arranged into Suzuki-Miyaura type cross-coupling reactions to produce biaryls in high yields.

Paragraph 0131; 0132-0136, (2017/05/02)
The invention provides an anthracene compound. The anthracene compound has a structure in the formula (I), wherein Q is the C1-60 alkyl group or the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; Ar is the C6-60 aryl group or the C5-60 condensed ring group or the C5-60 heterocyclic group; and Ar1 is H, the C1-60 alkyl group, the C1-60 alkoxy group, the C1-60 ether group, the C6-60 aryl group, the C6-60 condensed ring group, the C6-60 heterocyclic group and the C6-60 arylamine group. Compared with the prior art, the anthracene compound is connected with an aromatic compound through anthracene, and the Q, Ar and Ar1 groups are introduced, so that a device emits blue light after the organic compound is applied to the organic light-emitting device; and meanwhile, the means that the above groups are used for adjusting the light-emitting wavelength is adopted, the light-emitting efficiency of the organic light-emitting device is high, and the service life is long.
