일반 설명
1-Bromobenzocyclobutene is a useful synthon. It has important applications in organometallic methodology. Reaction between cycloheptatriene, bromoform, potassium carbonate and 18-crown-6 at 140°C yields 1-bromobenzocyclobutene.
애플리케이션
1-Bromobenzocyclobutene may be used in the synthesis of following compounds:
- five-membered zirconacycles
- benzocyclobutenol and benzocyclobutenone
- 2,3-dimethoxyprotoberberinium bromide, via reaction with 3,4-dihydro-6,7-dimethoxyisoquinoline

[reaction: see text] Commercially available 1-bromobenzocyclobutene is a potentially useful synthon particularly with the application of organometallic methodology. Here we show that it is readily converted into Cp(2)Zr(benzocyclobutadiene), which couples with alkynes or nitriles giving five-membered zirconacycles. Treatment of these
