ratio 28 : 72, but with propene only dimethyl-n-propylphosphine is produced. Bis(trifluoromethyl) phosphine gives only one adduct with each olefin. In all cases the product, or the major product where two are formed, is that predicted on the basis of formation of the most stable intermediate radical. Neither bis(trifluoromethyl)phosphine nor phosphine react with 1,1,3,3,3-pentafluoropropene under u.v. irradiation

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.
