Porous Cu-BTC silica monoliths as efficient heterogeneous catalysts for the selective oxidation of alkylbenzenes
Song, Guo-Qiang,Lu, Ying-Xun,Zhang, Qi,Wang, Fan,Ma, Xiao-Kun,Huang, Xian-Feng,Zhang, Zhi-Hui
, p. 30221 - 30224 (2014)
The microporous material Cu-BTC (1,3,5-benzenetricarboxylic acid, BTC) is a prototype metal-organic framework (MOF). In situ combination of Cu-BTC and macro-/mesoporous silica monoliths lead to an efficient catalyst for selective oxidation. The catalytic

ORGANO CYANOCUPRATES. II. REACTIONS AVEC LES CETONES α-HALOGENEES
Hamon, Louis,Levisalles, Jacques
, p. 259 - 272 (1983)
Comparison of lithium dimethylcuprate versus methylcyanocuprate as nucleophilic methylating reagents for α-halo ketones shows better selectivity for alkylation in the case of methylcyanocuprate, especially in the mixed solvent ether/dimethylformamide.The inverse addition techniques and addition of ligands such as dimethyl maleate also improve the selectivity.Methylcopper in the presence of chelating agents gives good selectivity but the reaction is slower.

One metal-free porphyrin, modified by electron-withdrawing groups, was synthesized by introduction of two peripheral pyridyl substituents and two metal coordination polymers, {[Zn(C42H16F10N6)]·2C2Hs
A Novel Open-Framework Copper Borovanadate with Enhanced Catalytic Performance for Oxidation of Benzylic C?H Bond
Feng, Yuquan,Zhong, Zhiguo,Wang, Hongwei,Fan, Huitao,Bi, Dongqin,Wang, Lu,Xing, Zhengzheng,Qiu, Dongfang
, p. 9962 - 9967 (2017)
A novel open-framework copper borovanadate, with a 6-connected topological net and 1D 8-membered ring channels, has been obtained for the first time. The compound not only exhibits a unique -B3O7(OH)-Cu-B(OH)3 linkage and

The dehydrative mono-/dialkylation reactions of alcohols and β-ketoacids were realized under arylboronic acid catalysis, furnishing a series of β-aryl ketones and β-ketoesters in yields of 15–99%, with CO2 and H2O being the byproduct
o-Quinone methide with overcrowded olefin component as a dehydridation catalyst under aerobic photoirradiation conditions
Uraguchi, Daisuke,Kato, Kohsuke,Ooi, Takashi
, p. 2778 - 2783 (2021/03/14)
Ano-quinone methide (o-QM) featuring an overcrowded olefinic framework is introduced, which exhibits dehydridation activity owing to its enhanced zwitterionic character, particularly through photoexcitation. The characteristics of thiso-QM enable the operation of dehydridative catalysis in the oxidation of benzylic secondary alcohols under aerobic photoirradiation conditions. An experimental analysis and density functional theory calculations provide mechanistic insights; the ground-state zwitterionic intermediate abstracts a hydride and proton simultaneously, and the active oxygen species facilitate catalyst regeneration.
