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 | DONE | spectroscopy-reference-tables — NMR 1H + 13C + heteronuclear + 2D chemical shifts, IR band positions, MS fragmentation patterns, UV-Vis chromophores; pairs with analytical-chemistry-methods |
| Functional group taxonomy | DONE | functional-groups-and-solvents (Part 1) — systematic enumeration of every functional group with pKa, IR signature, NMR signature, typical reactions |
| Solvent properties table | DONE | functional-groups-and-solvents (Part 2) — dielectric, BP, MP, dipole, Hildebrand δ, log P, density, miscibility, toxicity, green-chemistry replacements |
| Catalyst families catalog | DONE | catalyst-instrumentation-and-monomers (Part 1) — Pd / Ru / Rh / Ir / Mn / Fe / Cu / Ni / organocatalysts / NHCs / photoredox; chiral ligand families (BINAP, DuPhos, Josiphos, PHOX, salen) |
| Lab instrumentation catalog | DONE | catalyst-instrumentation-and-monomers (Part 2) — 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 |
| Monomer catalog | DONE | catalyst-instrumentation-and-monomers (Part 3) — monomers for polymer synthesis with Tg/Tm/density; polymer properties live in polymer-properties-and-applications |
| 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.
