Chemistry Tier 3 — Family Indexes
Tier 3 = exhaustive catalog notes that enumerate named entities (reactions, reagents, catalysts, instruments, polymers) with their key parameters, year of discovery, and selectivity tradeoffs. Tier 1 = foundational topic notes (see _index). Tier 2 = walkthroughs (synthesis route, mechanism deep-dive). Tier 3 = the lookup tables that Tier 1 + Tier 2 reference.
Scope
A Tier 3 family index in Chemistry should answer: “Show me every named X that practitioners actually use today, with the rough year, who’s credited, what it’s selective for, and what kills it.” If a query of the vault returns a Tier 1 note that mentions a named reaction without saying which selectivity it gives, the Tier 3 catalog is where that gap gets filled.
Status of Tier 3 catalogs
| Catalog | Status | Note |
|---|---|---|
| Reagent and reaction catalog | DONE | reagent-and-reaction-catalog — ~100 named reactions across C-C bond formation, functional-group manipulation, oxidation/reduction, asymmetric catalysis, click chemistry |
| Spectroscopy reference tables | DEFERRED | NMR 1H + 13C chemical shifts, IR band positions, MS fragmentation patterns; merges with analytical-chemistry-methods |
| Functional group taxonomy | DEFERRED | Systematic enumeration of every functional group with pKa, IR signature, NMR signature, typical reactions; overlaps reagent catalog |
| Catalyst families catalog | DEFERRED | Pd / Ru / Rh / Ir / Mn / Fe / Cu / Ni / organocatalysts / NHCs / photoredox — chiral ligand families (BINAP, DuPhos, Josiphos, PHOX, salen) |
| Lab instrumentation catalog | DEFERRED | HPLC (Waters, Agilent, Thermo), GC-MS, LC-MS Orbitrap (Thermo), NMR (Bruker AVANCE NEO 400–1200 MHz, JEOL), FTIR, UV-Vis, ICP-MS, XRD (Bruker D8, Rigaku), TGA-DSC |
| Solvent properties table | DEFERRED | Dielectric, BP, MP, dipole, donor number, miscibility, Hansen solubility parameters δD/δP/δH |
| Polymer and monomer catalog | DEFERRED | Commodity (PE, PP, PS, PVC, PET) + engineering (PC, PEEK, POM, PA) + biopolymers + monomers with Tg/Tm/density; overlaps polymer-chemistry |
| Battery cathode chemistries catalog | DEFERRED | LCO, NMC 811/622, NCA, LFP, LMFP, LMR-NMC, sodium-ion, solid-state; overlaps battery-chemistries — single canonical home TBD |
Convention
- All energies in kJ/mol primary; kcal/mol in parens.
- All temperatures in degrees Celsius primary; K in parens where standard state matters.
- All pressures in bar primary (1 bar = 100 kPa); atm in parens for legacy literature comparison.
- Concentrations in mol/L (M).
- ee = enantiomeric excess in percent.
- Named reactions cited with discoverer + year + Nobel year where applicable.
- Real commercial reagent product codes (Sigma-Aldrich, TCI, Strem, Alfa Aesar, Millipore-Sigma) when relevant.
