Highly Efficient and Diastereoselective Gold(I)-Catalyzed Synthesis of Tertiary Amines from Secondary Amines and Alkynes: Substrate Scope and Mechanistic Insights
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).
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.
