Abstract:
In this paper the synthetic methods and the substituent effects on yields were discussed. It was found that the yields were not high, and the compounds with electron-drawing groups had higher yields. Some compounds with electron-giving groups such as t-Bu couldn't be synthesized by wittig-horner method. The compounds were characterized by IR, 1H NMR, MS, UV and FL. The experimental results indicated that there was not quantitative substituent effect on IR, the electron-drawing groups had great effect on the chemical shifts of propenyl hydrogen and methyl hydrogen, the strong double-electron fragments existed in MS. Some experimental phenomena of UV and FL were also studied.
