, p. 5163 - 5172 (2019)
A new Zr(IV)-based UiO-67 metal-organic framework (1) was prepared with urea-functionalized biphenyl-4,4′-dicarboxylic acid (BPDC-urea) as the linker using conventional solvothermal technique and thoroughly characterized using X-ray powder diffraction (XR
Addition of pyrroles to electron deficient olefins employing InCl3
Yadav,Abraham, Sunny,Subba Reddy,Sabitha
, p. 8063 - 8065 (2001)
Pyrroles undergo conjugate addition with electron deficient olefins in the presence of a catalytic amount of indium trichloride at ambient temperature to afford the corresponding Michael adducts in excellent yields with high selectivity without polymerisa
Post-modified anionic nano-porous metal-organic framework as a novel catalyst for solvent-free Michael addition reactions

, p. 37036 - 37040 (2014)
By the strategy developed here, a novel application of anionic metal-organic frameworks as heterogeneous catalysts has been introduced. We have been able to prepare a cation exchanged anionic MOF as a new heterogeneous catalytic system for solvent-free Michael addition of pyrrole to electron-deficient β-nitrostyrenes. This catalyst was easily recovered and reused for at least six reaction cycles without a significant degradation in activity. the Partner Organisations 2014.
Silica gel, an effective catalyst for the reaction of electron-deficient nitro-olefins with nitrogen heterocycles
Shumaila, Abdullah M. A.,Kusurkar, Radhika S.
, p. 2935 - 2940 (2010)
The reaction of electron-deficient olefins with nitrogen heterocycles such as pyrrole and indole was examined in the presence of silica gel at room temperature under stirring at solvent-free conditions. It was found that silica gel is an effective catalys
Conjugate addition of pyrroles to α,β-unsaturated ketones using copper bromide as a catalyst
Kusurkar, Radhika S.,Nayak, Sandip K.,Chavan, Neelam L.
, p. 7323 - 7326 (2006)
Copper bromide was used as a catalyst for the addition of pyrroles to enones. When both the reactants were used in equimolar amounts, mono and dialkylated products were obtained. However, the use of excess enone furnished only dialkylated products. Thus,
Influence of oxophilic behavior of UiO-66(Ce) metal–organic framework with superior catalytic performance in Friedel-Crafts alkylation reaction

Feofanov, Mikhail N.,Averin, Alexei D.,Beletskaya, Irina P.
, p. 138 - 139 (2019/04/25)
The Friedel–Crafts reaction between electron-rich (het)arenes and β-nitrostyrenes under MgI2 or Ca(NTf2)2 catalysis affords 1-(het)aryl-2-nitro-1-phenylethanes in yields up to 94%.
Friedel-Crafts alkylation reaction with fluorinated alcohols as hydrogen-bond donors and solvents
Tang, Ren-Jin,Milcent, Thierry,Crousse, Benoit
, p. 10314 - 10317 (2018/03/26)
An effective and clean FC alkylation of indoles and electron-rich arenes with β-nitroalkenes in HFIP was reported. The desired products are formed rapidly in excellent yields under mild conditions without the need for any additional catalysts or reagents. Further, this methodology can be applied to one-pot synthesis of biologically active tryptamine derivatives.
TiCl2(OTf)-SiO2: A solid stable lewis acid catalyst for Michael addition of α-Aminophosphonates, Amines, Indoles and Pyrrole
Firouzabadi, Habib,Iranpoor, Naser,Farahi, Soghra
, p. 317 - 323 (2018/02/06)
TiCl2(OTf)-SiO2 is simply prepared by immobilization of TiCl3(OTf) on silica gel surface and introduced as a non-hygroscopic Lewis acid catalyst for C-N and C-C bond formation via Michael addition reaction. A variety of structurally diverse nitrogen nucleophiles including α-aminophosphonates, aliphatic and aromatic amines and imidazole were evaluated as Michael donors. Friedel–Crafts alkylation of indoles and pyrrole was also investigated through Michael addition reaction in the presence of TiCl2(OTf)-SiO2 as a catalyst. The reactions were conducted at room temperature or 60 °C under solvent-free conditions and the desired Michael adducts were obtained in high to excellent yields.
