praeparatio

NaH (7.5g,60% oleum dispersionis, 326mmol) addita massa per massam dodecyl -3-alkyni -1-alcohol (100g,54.95mmol; GF Smith) in commoto 0 solutione ethylenediaminis (40mL). Post 1h, temperatura ad 70 evectus est. Post aliam 8h, reactionem mixtionis ad 0°C refrigerare, cum aqua glacie frigida (100mL) diligenter terminare et cum aethere extrahere (3 60mL). Aether coniunctum extractum aqua ablutum est (100mL). Aqua lava erat cum aethere dorsum extracta (3 60mL). Composita extracta organica sub vacuo coacta erant et residua chromatographiae columnae subiecta utens 10% EtOAc/hexane ad 11-dodecyne -1-alcohol (7.4g,74%) contaminata cum 3-5% aliarum isomers regionalium ( regioisomer). TLC:30% EtOAc/hexane, Rf ≈ 0.4;1H NMR(300MHz,CDCl3)δ.66(t,2H,J = 7.3Hz), 2.14-2.21(m,2H),1.93(t,J = 1.9Hz. 1.20-1.63(m,16H).
