Concise synthesis of semicarbazides and formylhydrazines via direct addition reaction between aromatic azoarenes and N-substituted formamides

The addition reactions 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 conditions. This is the first successful example of direct addition of N-substituted formamides to a NN bond.

Palladium-catalyzed synthesis of α-iminoamides from imidoyl chlorides and a carbamoylsilane

A series of pure imidoyl chlorides were converted into α-iminoamides by treatment with a carbamoylsilane under catalysis by palladium(0) complexes.

Novel Synthesis of N,N-Diarylarylmethanamines from N-(Arylmethylene)arenamines and (Arylmethoxy)arenes

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 ether to its corresponding aldehyde.Side reactions and a proposed reaction mechanism are discussed.

Aromatic tertiary amines, enamines, deoxybenzoins and benzils

A novel synthesis of aromatic tertiary amines involves reacting an aromatic anil and an aromatic ether in a molar ratio of 1:1; adjusting the ratio to 2:1 produces novel enamines and by employing a two step process for enamine production, various unsymmetrically substituted enamines can be obtained which are readily hydrolyzed to corresponding deoxybenzoins which in turn are readily oxidized to benzils, the aromatic tertiary amines may be used to produce charge transport layers in xerography, while the benzils may be used to produce a variety of desired polymers.

A New Synthesis of 1,4-Diaryl-1,3-butadienes Utilizing the Anil Synthesis

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.
