Pyridine, 3-vinyl- - Reference Information
| Overview | the synthesis of carbon-carbon double bonds (C = C) has been a very important reaction in organic chemistry, in addition to the direct elimination reaction, there are four reaction pathways by which olefins containing carbon-carbon double bonds can be prepared: Wittig reaction, Peterson reaction, Julia-Lythgoe olefin synthesis reaction, and olefin metathesis reaction. Among these methods, the Wittig reaction, as one of the most common methods, has been widely used in organic synthesis since the reaction of aldehydes, ketones and phospholid reagents was reported by George Wittig in p53. |
| Use | 3-vinylpyridine is one of the compounds containing a carbon-carbon double bond (C = C), it can be used as a pharmaceutical synthesis intermediate. |
