| titleOfInvention | A kind of method that Catalyzed by Chitosan one kettle way prepares 2 thiocarbonyl 2H thiapyran derivatives |
| abstract | The invention discloses a kind of method that Catalyzed by Chitosan one kettle way prepares 2 thiocarbonyl 2H thiapyran derivatives, belong to technical field of chemical material preparation.The method that the Catalyzed by Chitosan one kettle way of the present invention prepares 2 thiocarbonyl 2H thiapyran derivatives, using aromatic aldehyde, malononitrile and carbon disulfide as reaction raw materials, 2 thiocarbonyl 2H thiapyran derivatives are directly generated by single step reaction under the catalytic action of chitosan catalyst, the mol ratio of aromatic aldehyde, malononitrile and carbon disulfide is 1 in reaction：(1~1.4)：1, the quality of chitosan catalyst in gram be aromatic aldehyde used by mM in terms of material amount 20~33%.Using technical scheme, enormously simplify the preparation technology of 2 thiocarbonyl 2H thiapyran derivatives, and catalyst activity it is high, it is biodegradable, can be recycled, raw material availability is high, and purification of products is easy. |
