Versuchsvorschrift
Prepared from (S)-1-bromo-4,5-difluoro-2-(pent-4-en-2-yloxy)benzene in 100% yield following the same procedure as (S)-(4-fluoro-2-(pent-4-en-2-yloxy)phenyl)boronic acid. NMR is complex and suggests an oligomeric mixture. The material, however, was used as is and was fully compentent for undergoing a Suzuki coupling.
