| Hazard Information | Back Directory | [Description]
1-Chloro-2-butene is a butenylating agent via Grignard and other organometallic reagents, organoborane compounds, other nucleophiles, and organosilane compounds. | [Chemical Properties]
colourless liquid | [Uses]
Crotyl chloride has been used:
- to investihgate the kinetics of the reactions of atomic chlorine with series of unsaturated aldehydes and ketones at 298K, to probe structure-reactivity relationships
- in the preparation of (E)-crotyltrichlorosilane
| [Preparation]
pure isomers of 1-Chloro-2-butene can be prepared by chloride displacement of corresponding alcohols via Ph3P in various solvents, and other chlorinating agents. | [General Description]
Crotyl chloride reacts with trichlorosilane in the presence of tertiary amine and copper salts to give the corresponding allyltrichlorosilanes. |
