Metal-free N-arylation of secondary amides at room temperature.
The arylation of secondary acyclic amides has been achieved with diaryliodonium salts under mild and metal-free conditions. The methodology has a wide scope, allows synthesis of tertiary amides with highly congested aryl moieties, and avoids the regioselectivity problems observed in reactions with (diacetoxyiodo)benzene.
متن کاملBorate esters as convenient reagents for direct amidation of carboxylic acids and transamidation of primary amides.
Simple borates serve as effective promoters for amide bond formation with a variety of carboxylic acids and amines. With trimethyl or tris(2,2,2-trifluoroethyl) borate, amides are obtained in good to excellent yield and high purity after a simple work-up procedure. Tris(2,2,2-trifluoroethyl) borate can also be used for the straightforward conversion of primary amides to secondary amides via tra...
متن کاملHighly chemoselective metal-free reduction of tertiary amides.
This communication describes the chemoselective metal-free reduction of tertiary amides to the corresponding amines. Hantzsch ester is used as a mild reducing agent for the reduction of trifluoromethanesulfonic anhydride activated amides providing the tertiary amines with high functional group tolerance.
متن کاملUltrasound-assisted synthesis of aliphatic acid esters at room temperature.
This work describes the ultrasound-assisted synthesis of saturated aliphatic esters from synthetic aliphatic acids and either methanol or ethanol. The products were isolated in good yields after short reaction times under mild conditions.
متن کاملManganese powder promoted highly efficient and selective synthesis of fullerene mono- and biscycloadducts at room temperature
Discovery of an efficient, practical, and flexible synthetic method to produce various important electron acceptors for low-cost organic photovoltaics (OPVs) is highly desirable. Although the most commonly used acceptor materials, such as PC61BM, PC71BM, IC60BA, bisPC61BM have been proved to be promising for the OPVs, they are still very expensive mainly due to their low production yields and l...
