ChemInform Abstract: Highly Efficient and Eco-Friendly Synthesis of Tertiary Amines by Reductive Alkylation of Aldehydes with Secondary Amines over a Pt Nanowires Catalyst.
A highly efficient and environmentally friendly method for the synthesis of tertiary amines by direct interaction of aldehydes with secondary amines was reported over a Pt NWs catalyst under mild reaction conditions.
Reaction of arylmethylenemalonaldehydes with tributylphosphine and tertiary amines affords compounds of dipolar structure whereas reaction with primary and secondary amines leads to 1,4-addition products. Salts of nucleophilic inorganic anions add to arylmethylenemalonaldehydes under formation of salts of substituted malonaldehydes.
For the one-pot reductive amination of benzaldehyde with nitrobenzene, intermetallic Ni2Si/SiCN from the decomposition of a nickel-modified polysilazane precursor exhibited high activity (>99%) and high selectivity (92% to aromatic amine).
Reductive alkylation of 2,5-dimethoxybenzoic
acid (1) with 2-(3',5'-dimethoxyphenyl)ethyl iodide (2) followed by
cyclodehydration and oxidative decarboxylation afforded orchinol (5) in high
overallyield. A simple synthesis
of iodide (2) based on the reductive alkylation of 3,5-dimethoxybenzoic acid
(6) was also developed.
Nano-sized CdS was successfully prepared, fully characterized and applied as a highly efficient reusable photocatalyst for the condensation of tertiary amines with double and triple bonds via a C–H activation approach.
