Palladium-Catalyzed Synthesis of α-Iminoamides from Imidoyl Chlorides and a Carbamoylsilane
摘要:
A series of pure imidoyl chlorides were converted into alpha-iminoamides by treatment with a carbamoylsilane under catalysis by palladium(0) complexes.

The anil synthesis was employed in the preparation of 1,4-diarylsubstituted 1,3-butadienes 7 from 1-arylpropenes 5 and N- arylideneanilines (aromatic Schiff bases) 6 in dimethylformamide solution and a strong base as catalyst obtained in situ by reacting metallic sodium with this solvent.
The additionreactions between aromatic azoarenes and N-substituted formamides are described. This direct and practical method provides a novel approach for the synthesis of formylhydrazines and semicarbazides in the presence of NaI/DTBP and imidazole/DCP catalytic systems, respectively. It can be seen that C–H or C–N from N-substituted formamides could be cleaved selectively under such transition-metal-free

Various N,N-diarylarylmethanamines were synthesized by the reaction of N-(arylmethylene)arenamines with (arylmethoxy)arenes in dimethylformamide solution in the presence of a strong base as a catalyst which is obtained in situ by reacting metallic sodium with this solvent. In general, the reaction may be depicted as the reduction of the imine and addition, on the original imino nitrogen atom, of the aryl group (of the aryloxy moiety) of the ether and presumably oxidation of the arylmethoxy group of the either to its corresponding aldehyde. Side reactions and a proposed reaction mechanism are discussed.
