The pka of water and H 3O+ have been experimentally determined to be 14.0 and 0.0, respectively. Earlier values of 15.7 and –1.74, respectively are erroneous numbers proposed by scientists who made some errors in the calculated “rational” values. See: 1) Helv. Chim. Acta 2014, 97, 1. and 2) J. Chem. Educ. 2017, 94, 690.

NMR Spectroscopy - Organic Chemistry Data
2020年2月14日 · This set of pages originates from Professor Hans Reich (UW-Madison) "Structure Determination Using Spectroscopic Methods" course (Chem 605). It describes Nuclear Magnetic Resonance (NMR) in details relevant to Organic Chemistry. It also includes NMR summary data on coupling constants and chemical shift of 1H, 13C, 19F, 31P, 77Se, 11B. Spectra (PDF form) of more than 600 compounds are also ...
weaker (pKa . 30) base than the dialkylamides above. Used where a delicate touch is needed (e.g. for enolate alkylation when halide is part of the molecule[3]) and where hydride reduction occurs with LDA. LiHMDS will give the thermodynamic enolate under appropriate conditions. Chiral Amide Bases.

Hans Reich's Research - Organic Chemistry Data
2024年11月24日 · Research Description. Our research effort is directed towards the study of organometallic and organometalloid compounds. The goal of the work is to deepen our understanding of these compounds and thus improve and extend their chemistry, as well as to discover new reactions of value for synthetic chemistry.
