Dibenzyls are essential building blocks that are widely used in organic synthesis, and they are typically prepared by the homocoupling of halides, organometallics, and ethers. Herein, we report an approach to this class of compounds using alcohols, which are more stable and readily available. The reaction proceeds via nickel-catalyzed and dimethyl oxalate assisted dynamic kinetic homocoupling of benzyl alcohols. Both primary and secondary alcohols are tolerated.

Page/Page column 34; 35-36, (2018/04/20)
The present subject matter relates to compositions containing and synthesis of fluorescent materials e made from tetraphenylethylene (TPE) derivative compounds exhibiting aggregation induced emission (AIE) properties. Further contemplated herein are applications for TPE derivative compounds such as electroluminescent devices since they have a high efficiency, low turn on voltage, and excellent brightness. Additionally, application of TPE derivatives exhibiting AIE properties in various fields such as OLEDs, fingerprinting and forensic technology, and various other biological and industrial sectors are discussed.

2-Hydroxy-2-methylpropiophenone undergoes a unique multiple arylation via C-C and C-H bond cleavages upon treatment with excess aryl bromides in the presence of a palladium catalyst to give 1,1,2,2-tetraarylethanes and 4,4-diaryl-1-phenylisochroman-3-ones. Copyright

Reported herein is a novel method on dechlorination coupling reaction of halides by using RuCl2(PPh3)3 catalyst under a hydrogen atmosphere with benzene as the solvent, which affords alkanes in excellent yields.
Ruthenium-catalyzed carbon-carbon formation to synthesize tetraarylethanes and tetraarylxylylene through dechlorinative dimeric reaction

Dechlorinative coupling-dimerization reaction is studied to synthesize alkanes by using tris-triphenylphosphine ruthenium (II) in the presence of hydrogen atmosphere. Two types of halides (α-chlorodiarylmethanes 1a-d and bis(chlorophenylmethyl)-1, 3-phenylene 6) are employed as substrates to form radical species and then dimerized to generate alkanes in high yields. To our knowledge, it is the first time that the formation of 1,1,2,2-tetraarylethanes and 1,2,9,10-tetraphenyl-di- m -xylylene over typical ruthenium-catalyzed dehalogenative coupling-dimerization conditions is reported.
