The field of isotope effects has expanded exponentially in the last decade, and researchers
are finding isotopes increasingly useful in their studies. Bringing literature on the subject up …

Intramolecular NH… O, S, N interactions in non-tautomeric systems are reviewed in a broad
range of compounds covering a variety of NH donors and hydrogen bond acceptors. 1H …

We have developed a new technology called multi-catalysis for the sequential one-pot
synthesis of highly functionalized heterocycles. A practical and novel multi-component …

This contribution describes the study of hydrogen bonding in secondary oxamides,
monothiooxamides, and dithiooxamides by ab initio calculations, X-ray diffractions, NMR …

NH chemical shift temperature coefficients have been measured in a large series of N-
substituted-3-piperidinethiopropionamides in which the N⋯ N distances are short but of …

A number of 5‐acyl rhodanines and thiorhodanines with bulky acyl groups (pivaloyl and
adamantoyl), not previously available, have been synthesized. The compounds are shown …

The title N-allylthioamides (1a-f) were synthesized in the reaction of allyl isothiocyanate with
enamines (1a-c) and 1, 3-diketones (1d-f), respectively, carried out in an acetonitrile solution …

A series of intramolecularly hydrogen-bonded N-substituted 3-(piperidine, morpholine, N-
methylpiperazine) thiopropionamides and some corresponding amides have been studied …

The chapter introduces isotope effects on chemical shifts. It also contains a description of
potential energy surfaces in relation to tautomeric equilibria focusing on zero point energies …
