Nucleophilic aromatic substitution reactions under aqueous, mild conditions using polymeric additive HPMC

The use of the inexpensive, benign, and sustainable polymer, hydroxypropyl methylcellulose (HPMC), in water enables nucleophilic aromatic subsitution (SNAr) reactions between various nucleophiles and electrophiles. The mild reaction conditions facilitate a broad functional group tolerance that can be utilized for subsequent derivatization for the synthesis of pharmaceutically relevant building blocks. The use of only equimolar amounts of all reagents and water as reaction solvent reveals the greenness and sustainability of the methodology presented herein.

ORGANIC REACTIONS CARRIED OUT IN AQUEOUS SOLUTION IN THE PRESENCE OF A HYDROXYALKYL(ALKYL)CELLULOSE OR AN ALKYLCELLULOSE

The present invention relates to a method of carrying out an organic reaction in aqueous solution in the presence of a hydroxyalkyl(alkyl)cellulose or an alkylcellulose.

Facile aromatic nucleophilic substitution (SNAr) reactions in ionic liquids: An electrophile-nucleophile dual activation by [Omim]Br for the reaction

A facile aromatic nucleophilic substitution (SNAr) reaction in recyclable [Omim]Br under relatively mild conditions has been described. An electrophile-nucleophile dual activation by [Omim]Br is also discovered based on control experiments, 1H NMR and IR spectroscopies. This chemistry provides an efficient and metal-free approach for the generation of Caryl-X (XS, N, O) bonds, many of which are significant synthetic intermediates or drugs, making this methodology attractive to both synthetic and medicinal chemistry.

Nucleophilic Aromatic Substitution Reactions in Water Enabled by Micellar Catalysis

Given the huge dependence on dipolar, aprotic solvents such as DMF, DMSO, DMAc, and NMP in nucleophilic aromatic substitution reactions (SNAr), a simple and environmentally friendly alternative is reported. Use of a "benign-by-design" nonionic surfactant, TPGS-750-M, in water enables nitrogen, oxygen, and sulfur nucleophiles to participate in SNAr reactions. Aromatic and heteroaromatic substrates readily participate in this micellar catalysis, which takes place at or near ambient temperatures.

Ligand-free solid supported palladium(0) nano/microparticles promoted C-O, C-S, and C-N cross coupling reaction

Ligand-free solid-supported nano and microparticles of Pd(0) (SS-Pd) were used as a heterogeneous catalyst in carbon-heteroatom bond formation reactions. Nitro substituted aryl halides reacted with oxygen, sulfur, and nitrogen nucleophiles to afford the corresponding products in good yields. A one-pot sequential cross coupling and nitro-reduction was also performed using the same SS-Pd catalyst to access amine substituted carbon-heteroatomic molecules. In addition, SS-Pd could be recycled up to seven runs without a significant loss of catalytic activity.

Synthesis of aryl sulfides by decarboxylative C-S cross-couplings

A study was conducted to demonstrate the transition-metal-catalyzed synthesis of aryl sulfides by decarboxylative C-S cross-couplings. Coupling reaction of 2-nitrobenzoic acid with 1-octanethiol were carried in the presence of different combinations of tr

CsF-Al2O3 mediated rapid condensation of phenols with aryl halides: Comparative study of conventional heating vs. microwave irradiation

Biaryl ethers and thio ethers are formed in high yields by the condensation of phenols and thiophenols with electron-deficient aryl halides using CsF supported on Al2O3 under microwave irradiation in solvent-free conditions.
