The invention discloses cis-cyclohexyl - 1, 2 - dicarboxylic imide synthetic method. In order to phthalimide and hydrogen as a raw material, under the catalysis of the catalyst prepared in high yield cis-cyclohexyl - 1, 2 - dicarboxylic imide. The invention through changing the process conditions to achieve the purpose of avoid side reaction, and finally achieves the high selectivity of the reaction, high conversion rate; reaction liquid through simple distillation, crystallization can be obtained filter means of 98% content product of the above; by adding is great and copper powder load alumina composite catalyst as a catalyst to catalyze the reaction, the reaction selectivity can reach 93.05%, yield can reach 94.11%.

A straightforward synthesis of 1,2-dicyanoalkanes by reacting nitroalkenes with trimethylsilyl cyanide in the presence of tetrabutylammonium fluoride is described. The reaction proceeds through a tandem double Michael addition under mild conditions. Employing the hypervalent silicate generated from trimethylsilyl cyanide and tetrabutylammonium fluoride is essential for achieving this transformation. Mechanistic studies suggest that a small amount of water included in the reaction media plays a key role. This protocol is applicable to various types of substrates including electron-rich and electron-deficient aromatic nitroalkenes, and aliphatic nitroalkenes. Moreover, vinyl sulfones were found to be good alternatives, particularly for electron-deficient nitroalkenes. The broad substrate scope and functional group tolerance of the reaction makes this approach a practical method for the synthesis of valuable 1,2-dicyanoalkanes.

The synthesis and some of the physical properties of the first poly(disulfidediamines) are reported. The disulfidediamine functional group (R2NSSNR2) possesses a disulfide bond in a unique environment that leads to a low bond dissociation energy (calculated BDE of 43.1 kcal mol-1). These polymers were synthesized in high yields and with conversions up to >98% by reactions between secondary diamines and a new disulfide monomer. The disulfide monomer was synthesized in two steps without the need for column chromatography. The polymerizations were robust and completed at room temperature, under ambient atmospheric conditions, and in solvents that were used as purchased. These polymers were stable, but they rapidly decomposed under acidic, aqueous conditions or by heating to 175 °C as shown by thermal gravimetric analysis. The first fully conjugated poly(disulfidediamine) was synthesized, and its electrical conductivity was characterized in the solid state.
