What is 1-Bromo-1-propene (cis and trans)?
Chemical properties
CLEAR COLOURLESS TO LIGHT YELLOW LIQUID
The Uses of 1-Bromo-1-propene (cis and trans)
1-Bromo-1-propene upon n-BuLi treatment generates the propynyllithium anion, in situ, which later undergoes nucleophilic addition reactions. Some of its other applications are:
- Synthesis of organic reagents such as methyl but-2-ynoate and 1-iodopropyne.
- Preparation o f intermediates in the total synthesis of (+)-aphanamol I and skyllamycins A-C.
- Synthesis of allylated pyrazoles, aryl alkynyl sulfides and allenamides.
The Uses of 1-Bromo-1-propene (cis and trans)
1-Propenyl bromide is a useful building block, especially when a 3 carbon addition is required, such as its use in the synthesis of the pharmaceutical spilanthol.
