Reductive alkylation and reductive methylation of aromatic primary amines with carbonyls and 37% formaldehyde using decaborane in one-pot way gave the corresponding tertiary amines in high yields. The reaction condition was extended for the reduction of n

A magnetically recoverable, efficient and selective copper based nanocatalyst has been synthesised via covalent grafting of 2-acetylthiophene on a silica coated magnetic nanosupport followed by metallation with copper acetate. The obtained organic-inorganic hybrid nanomaterial has been characterized by electron microscopy techniques (SEM and TEM with EDS), XRD, VSM, FT-IR and AAS. The catalytic performance of the novel nano-catalyst is evaluated in the active transformation of various aromatic amines to industrially-important alkylated amines. The nanocomposites afford high turnover frequency and high selectivity for amines under aerobic conditions. Furthermore, the heterogeneous nature of the catalyst allows easy magnetic recovery and regeneration, which makes the present protocol highly beneficial to address the industrial needs and environmental concerns.

N,N-Dialkyl aromatic amines with a variety of ring substituents are N-dealkylated and N-nitrosated efficiently by n-butyl nitrite/ammonium chloride/water at reflux temperature.Ring nitrosation was never observed, but minor amounts of m- and p-nitro amines and/or nitrosamines were formed in some cases.Ring nitration is rather a reaction of the initial substrate than a process occurring on formed nitrosamines.The leaving propensities of the initial N-substituents to yield nitrosamines were in the order benzyl >> methyl >> alkyl.Key Words: Nitrosamines; N-Dealkylation; N-Nitrosation; C-Nitration; Alkyl nitrite.
