[Rh(Cod)Cl]2/Pph3?catalyzed dehydrogenative silylation of styrene derivatives with NBE as a hydrogen acceptor

Direct synthesis of arylalkenylsilanes by [Rh(COD)Cl]2/ PPh3-catalyzed dehydrogenative silylation of styrene derivatives with R3SiH (R = alkyl, alkoxy, aryl) was realized, in which norbornene (NBE) and PPh3 play a key role in achieving excellent selectivity in the formation of dehydrogenative silylation products. Moreover, this high-yielding transformation exhibits a broad substrate scope and good functional group tolerance.

Palladium-Catalyzed Mizoroki-Heck Reaction of Nitroarenes and Styrene Derivatives

We have developed a Mizoroki-Heck reaction of nitroarenes with alkenes under palladium catalysis. The use of a Pd/BrettPhos catalyst promoted the alkenylation, whereas other catalysts led to a decrease in the product yield. In addition to nitroarenes, nitroheteroarenes were also applicable to the present reaction. The combination of a nucleophilic aromatic substitution (SNAr) with the denitrative alkenylation produced a multifunctionalized arene in a one-pot operation.

Controlled light-mediated preparation of gold nanoparticles by a Norrish type i reaction of photoactive polymers

Gold nanoparticles (AuNPs) are subjects of broad interest in scientific community due to their promising physicochemical properties. Herein we report the facile and controlled light-mediated preparation of gold nanoparticles through a Norrish type I reaction of photoactive polymers. These carefully designed polymers act as reagents for the photochemical reduction of gold ions, as well as stabilizers for the in situ generated AuNPs. Manipulating the length and composition of the photoactive polymers allows for control of AuNP size. Nanoparticle diameter can be controlled from 1.5 nm to 9.6 nm. Instant preparation of Au nanoparticles! Mixing a photoactive polymer with HAuCl4 and NaOH in DMF/H2O and irradiating with light for a few minutes provides stable, spherical, polymer-coated Au nanoparticles with defined diameter. The diameter can be adjusted from 1.5 to 9.6 nm by varying the length and composition of the photoactive polymer.

Copper-catalyzed amidation of acids using formamides as the amine source

Copper-catalyzed amidation of acids with formamides or acetamide for the selective synthesis of amides with the aid of 1,4-diazabicyclo[2.2.2]octane as the ligand and tert-butyl hydroperoxide as the oxidant is presented. This method is highly compatible with a wide range of acids, including alkyl acids, aryl acids, α,β-unsaturated acids, and amino acids. A general and direct route for the synthesis of amides is described. The reaction involves the copper-catalyzed amidation of acids, wherein various formamides and an acetamide are used as the amine source. Importantly, this method represents a new strategy for the direct use of acids in the synthesis of amides. DABCO = 1,4-diazabicyclo[2.2.2]octane, TBHP = tert-butyl hydroperoxide. Copyright

A novel method for the conversion of carboxylic acids to N,N-dimethylamides using N,N-dimethylacetamide as a dimethylamine source

A simple, cost effective and environmentally benign method is reported for the preparation of N,N-dimethylamides from carboxylic acids. The versatility of the method is determined by synthesising a large number of N,N-dimethylamide derivatives. Carboxylic acids are heated at 160-165°C in N,N-dimethylacetamide solvent in the presence of1,1'-carbonyldiimidazole to afford the corresponding N,N-dimethylamides in good to excellent yields.
