Darstellung und Eigenschaften von und Reaktionen mit metallhaltigen Heterocyclen, XLVII. Darstellung und Eigenschaften 2,3‐substituierter Butan‐1,4‐diyl‐bis(trifluormethansulfonate)

Preparation and Properties of, and Reactions with, Metal‐Containing Heterocycles, XLVIII. Preparation and Properties of 2,3‐Substituted Butane‐1,4‐diyl Bis(trifluoromethanesulfonates) The bis(trifluoromethanesulfonates) [F 3 CSO 2 OCH 2 CR 1 R 2 −] 2 ( 4a–c ) [R 1 ,R 2 = D,D ( a ), CH 3 ,CH 3 ( b ), H,Br ( c )], cyclo‐C 6 H 10 (CH 2 OO 2 SCF 3 ) 2 ( 5 ) and [F 3 CSO 2 OCH 2 C‐(CH 2 )−] 2 ( 6 ) are obtained from the diols [HOCH 2 CR 1 R 2 −] 2 ( 1a–c ), cyclo‐C 6 H 10 ‐(CH 2 OH) 2 ( 2 ) and [HOCH 2 C(CH 2 )−] 2 ( 3 ) with (CF 3 SO 2 ) 2 O in the presence of pyridine. 6 is extremely unstable. 4–6 are characterized by their mass. 1 H, and 13 C{ 1 H} NMR spectra.
