Dimethyl- and bis(trifluoromethyl)-phosphines react smoothly with olefins under u.v. irradiation to give products R12PR2(R1= CF3, R2= Et, Prn, Bun, CHMeEt, or CF2·CHF2; R1= Me, R2= Et, CF2·CHF2′ or CF2·CHFCI) which are in accord with a free-radical mechanism in which the phosphino-radical R12P attacks the olefin to give the most stable intermediate radical.
二甲基和双(三氟甲基)-phosphines与烯烃反应顺利紫外光照射下,得到产品研发1 2 PR 2(R 1 = CF 3,R 2 =乙基,丙基Ñ,卜Ñ,CHMeEt,或CF 2 ·CHF 2; R 1 = Me,R 2 = Et,CF 2 ·CHF 2'或CF 2 ·CHFCI),这与自由基机理有关,其中膦基自由基R 1 2 P攻击烯烃以得到最大的稳定的中间自由基。
