- Corresponding amine nitrile and method of manufacturing thereof
-
The invention relates to a preparation method of nitrile. Compared with the prior art, the preparation method has the characteristics of obvious reduction of the usage amount of ammonia sources, low environmental pressure, low energy consumption, low production cost, high purity and yields of nitrile products, and the like, and can be used for obtaining nitrile with a more complex structure. The invention also relates to a method for preparing corresponding amine with nitrile.

- A COMBINED AB INITIO AND GAS ELECTRON DIFFRACTION STUDY OF THE MOLECULAR STRUCTURE OF 1,1-DICYANOCYCLOBUTANE
-
The molecular structure of 1,1-dicyanocyclobutane was investigated by gas electron diffraction and the results are compared with 4-21G ab initio gradient geometry refinements.In the cyclobutane ring C1-C2 > C2-C3 in contrast to structural trends generally observed for cyclobutyl systems with a single electronegative substituent.The C-CN groups are slightly non-linear, with the CN groups bent away from one another.The structural features observed can be rationalized in terms of a special electronic interaction between the geminal cyano groups, which is also suggested by the 13C NMR spectrum.
