3-methylbut-2-enyl (Z)-2-methylbut-2-enoate

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A mixture of 19.6 g. of methyl angelate, 22.2 g. of 3-methyl-2-butenyl alcohol, 100 ml. of toluene and 1.6 g. of dioctyltin laurate was placed in a glass flask which was equipped with a Soxhlet extractor filled with molecular sieve 4A on the top and a reflux cooler. The mixture was heated under reflux while returning the refluxed liquid through the molecular sieve 4A to the flask. The mixture obtained from the heating for a total of 26 hours was subjected to single distillation to give 24.24 g. of a distillate boiling at 102°-105° C. (25 mmHg). A mixture of 19.6 g which was equipped with a Soxhlet extractor The mixture was heated under reflux The mixture obtained from the heating for a total of 26 hours was subjected to single distillation to give 24.24 g

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
