Synthesis of 2-(2,4-Dichlorophenyl)-valeraldehyde Sun Xiaohong a,b,
Song Jirong a, Ma Haixia a, Wang Huifang b Abstract A
new compound of 2-(2,4-dichlorophenyl)-valeraldehyde was conveniently synthesized from
2,4-dichlorobutyrophenone and sulfonium methylide to form the corresponding
2-(2,4-dichlorophenyl)-1,2-epoxy-pentane and then through isomerization to form the title
compound. This new compound was reported first time. It was determined by the elemental
analysis, IR and 1H NMR spectra. The mechanism of the isomerization was
discussed also. 2-(2, 4-二氯苯基)-戊醛的合成研究 孙晓红a,b 宋纪蓉a
