S8-S9 · Section 2.1 Synthesis of Ligands · Scheme S1

Metal precursorsnone
Linker precursors4,5-dimethoxy-1,2-benzenediamine; 2,4,5-trimethoxybenzoic acid; compound 1 intermediate
Solventschloroform; DCM; water; chloroform/toluene for crystals
AdditivesPh3PCl2; HCl; NaHCO3; MgSO4; BBr3
Atmospherenitrogen during BBr3 demethylation
Temperaturereflux for amidation; 0 C addition then room temperature for demethylation
Time17 h amidation; 12 h demethylation
Oxidant / reductantBBr3 demethylation reagent
Work-uppoured into ice-cold water, extracted with DCM, acid/base washes, brine, dried over MgSO4, silica gel column; demethylation poured into ice water, filtered, washed with water
Activationnone reported for ligand
Scalability contextStep yields: 93% for compound 1 and 94% for 6OH-HBB; main text states 93% over two steps, which is inconsistent with SI step yields.
