Abstract

Abstract Reactions of iodides I (CH 2) m R f8 [m= 2− 4; R f8=(CF 2) 7 CF 3] and LiPH 2· DME (− 45 C, THF) give the primary phosphanes PH 2 (CH 2) m R f8 (7− 9; 48− 76%). Radical- initiated reactions (100 C) of 7 and H 2 C= CHCH 2 R f8, 8 and H 2 C= CHR f8 or H 2 C= CHCH 2 CH 2 R f8, and 9 and H 2 C= CHCH 2 R f8, give the title phosphanes P [(CH 2) m R f8] 2 [(CH 2) m′ R f8][m/m′= 2/3 (10), 3/2 (11), 3/4 (12), 4/3 (13); 70− 76%].
