Yield:7051-34-5 77.5%
Reaction Conditions:
with bromine;triphenylphosphine in N-methyl-acetamide
Steps:
1 Example 1
Example 1 (for comparison) 1250 ml of dimethylformamide were placed into the reaction vessel, and then 280.8 g of triphenylphosphine and then 70 g of hydroxymethylcyclopropane were added, the mixture was stirred for 30 minutes at room temperature under a nitrogen atmosphere, and the solution was subsequently cooled to -10° C. Then, 158.3 g of bromine (that is to say 2 mol % more than theoretically required) were metered in in the course of 4 hours. The reaction mixture was worked up by distillation. Bromomethylcyclopropane was obtained in a yield of 77.5% of theory. The purity of the product was over 97%, the open-chain halogenoalkanes amounted to 0.6%.
