Interpretation and prediction of organic reactions are often complicated by the entanglement
of electronic, ste-ric, and a variety of other effects. In 1963, Pearson1 brought forth a unifying …

196 JH FORSEERG tion was well characterized only in association with oxygen donors, as
exemplified by the polyaminepofycarboxylates and 8-quinolinolates. The observation that …

Rare-earth β-diketonates are complexes of β-diketones (1, 3-diketones) with rare-earth ions.
These complexes are the most popular and the most intensively investigated rare-earth …

In Table I are listed several olefins for which the prod-ucts have been characterized and
absolute yields de-termined. Two equivalents of CAN (ca. 1 M) in acetonitrile was added to a …

The number of possible applications of NMR spectroscopy has rapidly increased during the
past few years. New fields of applications have been opened by the development of …
