(Bromomethyl)cyclopropane Chemical Properties,Usage,Production

Uses

(Bromomethyl)cyclopropane is used in the synthesis of 1,4-dienes by iron-catalyzed cross-coupling with alkenyl Grignard reagents.

Description

(Bromomethyl) cyclopropane is a cyclopropane derivative. It can be used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1, 4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.

Chemical Properties

Colorless to yellow liquid

Uses

(Bromomethyl)cyclopropane was used as a synthetic building block for the introduction of the cyclopropylmethyl group. It was also used in the synthesis of 1,4-dienes via iron-catalyzed cross-coupling with alkenyl Grignard reagents.

Synthesis Reference(s)

Tetrahedron Letters, 13, p. 2135, 1972 DOI: 10.1016/S0040-4039(01)84787-0

General Description

The coupling reaction of (bromomethyl)cyclopropane with phenylmagnesium bromide was studied.

Synthesis

2516-33-8

7051-34-5

Example 1 (control experiment): 1250 mL of dimethylformamide (DMF) was added to the reaction vessel under nitrogen protection, followed by 280.8 g of triphenylphosphine. 70 g of hydroxymethylcyclopropane was added with stirring and the reaction was carried out at room temperature for 30 minutes. After cooling the reaction solution to -10°C, 158.3 g of bromine (102% of the theoretical amount) was slowly added dropwise over a period of 4 hours. Upon completion of the reaction, the reaction mixture was purified by distillation to afford bromomethylcyclopropane in 77.5% yield (based on theoretical values) with a product purity of >97%, which contained 0.6% open-chain haloalkanes.
