The regioisomeric triphenylaminoethanols - Comparison of their efficiency in enantioselective catalysis
Braun, Manfred,Fleischer, Ralf,Mai, Brigitte,Schneider, Marc-Andre,Lachenicht, Stefan
, p. 474 - 482 (2004)
Both enantiomers of the novel amino alcohol (R)- and (S)-2 are prepared from the corresponding enantiomer of the mandelic acid-derived ethanediol 3. The regioisomeric amino alcohols 1 and 2 are converted into the imines 7 and 8, respectively. Titanium com
Reactions on Aromatic Olefins Induced by Aminium Salts: Protic-Acid or Radical Cation Catalyzed Processes
Ciminale, Francesco,Lopez, Luigi,Mele, Giuseppe
, p. 12685 - 12696 (1994)
Aromatic olefins by reaction with aminium salts lead, in strongly acidic reaction media, to different reaction products, arising from the intermediate formation of carbocation or radical-cation species.
Palladium-catalyzed multiple arylation of phenyl ketones with aryl bromides

, p. 657 - 661 (1998)
The acidity constant, pQ(a)(E) = 8.49, for the stable thioenol, triphenylethenethiol, was determined by spectrophotometric titration, and that, pQ(a)(E) = 11.37, for its unstable oxygen analog, triphenylethenol, was determined by analysis of its ketonizat

Chemoselectivity of Pinacol Rearrangement Originate by Different Hexafluoroantimonate Oxidant
Chen, Xiaoyu,Wu, Chunlei,Li, Jia,Li, Yue
, p. 22 - 26 (2019)
Using 1,1,2-triphenylethane-1,2-diol, AgSbF6, and NOSbF6, two different carbonyl products of rearrangement were synthesized: neutral ketone compound 1,2,2-triphenylethanone (1) from NOSbF6 and coordination complex of Ag io
Strongly Entangled Triplet Acyl-Alkyl Radical Pairs in Crystals of Photostable Diphenylmethyl Adamantyl Ketones
Garcia-Garibay, Miguel A.,Hipwell, Vince M.,Park, Jin H.,Rivera, Edris A.
, p. 8886 - 8892 (2021/06/28)
Radical pairs generated in crystalline solids by bond cleavage reactions of triplet ketones offer the unique opportunity to explore a frontier of spin dynamics where rigid radicals are highly entangled as the result of short inter-radical distances, large
Method for preparing alpha-aryl ketone compound by using palladium complex

Paragraph 0028; 0034-0037, (2021/07/17)
The invention relates to a method for preparing an alpha-aryl ketone compound by using a palladium complex, which comprises the steps of in the presence of alkali, taking ketone and halogenated hydrocarbon as raw materials, taking the palladium complex containing an ortho-carborane benzothiazole structure as a catalyst, and carrying out alpha-halogenation reaction at room temperature to prepare the alpha-aryl ketone compound. Compared with the prior art, the palladium complex containing the ortho-carborane benzothiazole structure is applied to catalysis of the alpha-halogenation reaction of ketone and halogenated hydrocarbon, the alpha-aryl substituted ketone compound is prepared through a one-pot method, synthesis of the alpha-aryl ketone compound at room temperature by using simple, easily available and cheap raw materials is achieved, and the method has the advantages of low catalyst use equivalent, mild reaction conditions, more catalytic substrates, high substrate universality and high yield.
