HCID 123357166(S)-(5-fluoro-4-methyl-2-(pent-4-en-2-yloxy)phenyl)boronic acidYield 100%

Procedure

Prepared in 100% yield from (S)-1-bromo-5-fluoro-4-methyl-2-(pent-4-en-2-yloxy)benzene following the procedure for (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.
