“…4-Cyano-4-[(dodecylsulfanylthiocarbonyl)sulfanyl] pentanoic acid (CDSTSP), 48 5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heptadeca-uorododecan-1-ol, 49 and 5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heptadeca-uorododecan-1-amine 50 were prepared according to the literature. (5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-Heptadeca-uorododecyl)-1H-pyrrole-2,5-dione (R F Mi, 3). To a magnetically stirred solution of triphenylphosphine (1.90 g, 7.21 mmol) in THF (anhydrous, 50 cm 3 ) was added diisopropyl azodicarboxylate (1.46 g, 7.21 mmol) under a N 2 atmosphere at À78 C. The mixture was stirred for 10 min, and another solution of 5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,12-heptadecauorododecan-1-ol (4.26 g, 8.65 mmol) in THF (8 cm 3 ) was added to the mixture at À78 C. Maleimide (0.700 g, 7.21 mmol) was then added to the solution, and the reaction mixture was allowed to warm up to ambient temperature.…”
