in tert-butyl alcohol

Steps:

P.3.1 1.
1. Synthese von Divinylether In a100 mL two-neck flask equipped with a magnetic stirrer and a distillation bridge, 9.39 g (83.7 mmol) potassium tert-butylat in 40 mL wasserfreiem tert-Butanol are introduced and heated to 50 °C. By using a septum, 6.0 g (41.9 mmol) 2-chloroethyl ether is added dropwise to the mixture which is heated to 100 °C erhitzt. The reaction mixture becomes turbid. The Die distillation head is cooled with acetone/dry ice. GC/MS: m/z 70 (M+), 44 (C2H4O2+), 43 (C2H30+), 31 (CH30+), 27 (C2H3+). ¹H-NMR(200 MHz, CDCl₃): d 6.51-6.41 (dd, 2H, RO-CH=CH₂), 4.62-4.54 (dd, 2H, RO-CH=CH₂), 4.29-4.25 (dd, 2H, RO-CH=CH₂) ppm.
