EXAMPLE 1 Preparation of 1-Phenyl-2-(4-Benzocyclobutyl)ethene STR17 A solution of 2.4 g 4-bromobenzocyclobutane, 1.4 g styrene, 2.4 g tri-n-butylamine, 29 mg palladium (II) acetate, 100 mg of tri-o-tolylphosphine and 10 ml acetonitrile is stirred under nitrogen atmosphere at reflux for three hours. The reaction mixture is poured into 60 ml 10 percent HCl. The product is isolated by filtration, dried, recrystallized in ethanol, and isolated. About 2.10 g of greenish monomer product is prepared.
The synthetic route of 1073-39-8 has been constantly updated, and we look forward to future research findings.
