Umsetzungen von CF₃XXCF₃(X = S, Se) mit Phosphorigsäureestern

Abstract

Reactions of CF 3 SSCF 3 (X = S, Se) with the Esters of Phosphoric Acid Reactions of CF 3 XXCF 3 (X = S, Se) with (CH 3 O) 2 PR give CF 3 SP(O)(OCH 3 )R [1a: R = CH 3 O, 1C: R = CH 3 ) 2 N]. Similarly CF 3 SeSeCF 3 reacts with (CH 3 O) 3 P to form the corresponding CF 3 SeP(O)‐(OCH 3 ) 2 (2a). If CF 3 SSCF 3 is combined with (C 2 H 5 O) 2 P(O)H good yields of CF 3 SP(O)(OC 2 H 5 ) 2 ( 1b ) are obtained. On heating 1b decomposes to FP(O)(OC 2 H 5 ) 2 . IR and 19 F NMR data of the newly prepared substances are presented.
