alkyl halidesphotocatalysisα-Branched amines represent essential building blocks for organic synthesis. They are traditionally prepared through nucleophilic addition to imines. These methods often require highly reactive organometallic reagents and proceed under rigorous air- and moisture-free conditions. Here ...
Here we show that the selective N-alkylation of amines with alcohols can be catalysed by defined PNP manganese pincer complexes. A variety of substituted anilines are monoalkylated with different (hetero)aromatic and aliphatic alcohols even in the presence of other sensitive reducible functional ...
Active-copper-promoted mild and expeditious N-arylations of amines, amides, imides, and β-lactams with aryl halides under microwave irradiation conditions... L Yadav,B Yadav,V Rai - 《Cheminform》 被引量: 61发表: 2006年 Anodic oxidation of N-alkyl-lactams The anodic oxidation of N-alkyl-...
Although the N-alkylation of aliphatic amines with alkyl halides has been widely adopted for over 100 years, catalyst poisoning and unfettered reactivity have been preventing the development of a catalyst-controlled enantioselective version3,4,5. Here we report the use of chiral tridentate anionic ...
Alkylation of the anion with alkyl halides gave two series of isocyanide complexes: neutral [Fe(CN)(C5H5)(CO)(CNR)] and cationic [Fe(C5H5)(CO)(CNR)]+. The reaction of potassium cyanide with [WCl(C5H5)(CO)3] gave [W(CN)(C5H5)(CO)3] and K[W(CN)2(C5H5)(CO)2]; [MoCl(C5H5)...
Conventionally these reactions have been executed by SN2 reaction of amines with alkyl halides or by reduction of secondary amines [2]. The use of toxic reagents and complex work-up procedures in these conventional methods leads to generation of high levels of waste and has other environmental ...
By sulfonation, alkylbenzene sulfonate is produced; marketed in powder and liquid form, it has excellent detergent and cleaning properties and produces high foam.Read More amines In amine: Occurrence and sources of amines …are typically made by direct alkylation of secondary amines by alkyl halides...
