说明

General description

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.

Application

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
