Re-inventing the wheel. Instead of a #ChemEd #Chemistry summary, here is my attempt at a pKa (in H2O) scale. Values are taken from the Evans/Ripin & Hans Reich resources. If you want a table, I recommend these. This was an attempt at a more visual representation of the same data.

Finally, RADICAL CROSS COUPLING without the exogenous REDOX. We disclose in @ChemRxiv (chemrxiv.org/engage/chemrxi…) a broadly general platform for achieving transformations that normally required excess metallic or chemical reducing agents or photochemical setups (and their requisite catalysts) or potentiostats for electrochemistry. Now, such transformations can be accomplished with the same ease that one conducts a Suzuki coupling. You can scale up (its homogeneous) or scale down (use cheap parallel screening plates). Moisture is tolerated and base metal catalysis is used. As the best engineers like to say, "The best part is no part". Now, chemists have the option to remove the redox part from radical couplings. Quick Summary: Sulfonyl hydrazides are disclosed as versatile radical precursors as exemplified with seven new C–C bond forming, redox-neutral cross-couplings with: (1) activated olefins, (2) alkyl halides, (3) redox active esters, (4) aryl halides, (5) alkenyl halides, (6) alkynyl halides, and (7) a trifluoromethylating reagent to forge C(sp3)-C(sp3), C(sp3)-C(sp2), and C(sp3)-C(sp) bonds. Sulfonyl hydrazides are stable and usually crystalline substances that can be accessed in a variety of ways including transiently from hydrazones to achieve a net reductive arylation of carbonyl compounds. Exogenous redox (chemical, photo/electrochemical) additives are not necessary as these functional groups serve the dual role of radical precursor and electron donor. The operational simplicity (homogeneous, water tolerant, dump-and-stir) and practicality of the method are demonstrated as well as applications to streamlining synthesis and mild late-stage functionalization.

Here's the peer-reviewed version of our study into the change of molecular complexity over time @AstraZeneca Macclesfield. We examine many metrics and discuss how they compare and could be used. We also show applications in FDA historical data. pubs.acs.org/doi/full/10.10…
