s are used to introduce directly the 2-oxophosphonate 1-fluorinated synthons on organometallic reagents. A Horner reaction of the derivated anions with aldehydes gave various 2-fluoro-2-enones. Application to the cis, trans caronaldehyde ethyl esters led to the 2-fluoroethenyl pyrethroid derivatives.
二烷基膦酰氟乙酰氯用于将2-氧代膦酸酯1-氟化的合成子直接引入有机金属试剂中。衍生的阴离子与醛的霍纳反应得到各种2-氟-2-烯酮。应用于顺式,反式-甲醛醛乙酯可生成2-氟乙烯基拟除虫菊酯衍生物。
