Description
4-n-heptylbenzene boronic acid is an arylboronic acid built on a benzene core, carrying a heptyl chain. It serves as the nucleophilic partner in Suzuki-Miyaura cross-coupling, transferring its aryl group to a palladium centre under basic conditions.

What the substitution pattern does
The heptyl chain places this compound at n=7 in its homologous series. Chain length is not a cosmetic variable here: each added methylene lowers the melting point unevenly and shifts the balance between nematic and smectic order, because an odd-numbered chain sets its terminal bond at a different angle to the molecular long axis than an even one. Homologues therefore alternate in behaviour rather than trending smoothly, and an odd-numbered member frequently outperforms both of its neighbours for a given formulation.
Typical applications
- late-stage arylation in medicinal and agrochemical discovery routes
- Chan-Lam C-N and C-O couplings under copper catalysis
- conversion to the matching potassium trifluoroborate for storage-stable stock
- Suzuki-Miyaura cross-coupling with aryl halides and triflates
- construction of biphenyl and terphenyl cores for liquid crystal mixtures
