General Description

2-(bromomethyl)buta-1,3-diene, also known as bromomethylbutadiene, is a chemical compound with the molecular formula C6H9Br. It is a derivative of butadiene, which is a colorless gas commonly used in the production of synthetic rubber. The addition of a bromomethyl group to butadiene creates a compound with enhanced reactivity, making it valuable in chemical synthesis and as a building block for the production of various organic compounds. Bromomethylbutadiene is commonly used in the development of pharmaceuticals, agrochemicals, and advanced materials, and it is important to handle it with caution due to its potential toxicity and reactivity.

A General Method for the Synthesis of 2-Alkyl Substituted 1,3-Dienes Starting from 2-(Chloromethyl)-3-tosylpropene

The alkylation of the monolithium derivative 5 of 2-(chloromethyl)-3-tosylpropene (1) with bromo- or iodo-methyltrimethylsilane affords the β-silyl sulfone 7, which after nucleophilic substitution of the chlorine atom followed by β-elimination of tosyltrimethylsilane, promoted by tetrabutylammonium fluoride (TBAF), gives 2-substituted conjugated dienes 6 and the outer-ring diene 14.Racemic ipsenol (10b), an aggregation pheromone of the bark beetle Ips paraconfusus Lanier, is prepared.
