benzene-1,3,5 tricarbaldehyde; Synthesis Route ..
1,3,5-Tribromobenzene is used as an intermediate for active pharmaceutical ingredient manufacturing. It acts as an intermediate for the preparation of 1,3,5-trimethoxytoluene. It forms molecular complexes with -and  fullerenes. Further, it is employed as an internal standard during derivatization step in the determination of cyanide in human plasma and urine by gas chromatography-mass spectrometry. In addition to this, it reacts with the perfluoroalkenylzinc reagent in the presence of tetrakis(triphenylphosphine)palladium catalyst to yield a trifunctional monomer 1,3,5-tris(alfa, beta, beta-trifluorovinyl)benzene.
Sonogashira coupling of14 with 1,3,5-tribromobenzene has produced 13 in reasonableyields, but reproducibility of this reaction has been an issue.

Precursor 2may be prepared by Sandmeyer-type chemistry from a template–tricrescentmolecule prepared by Sonogashira coupling of three crescent units to1,3,5-triethynylbenzene (3).
Ourefforts aim to explore the utility of the 1,3,5-triethynylbenzene moiety as atemplate for generating complex, shape-persistent structures in which theperipheral aryl systems are locked in coplanar and orthogonal conformations.
