The second phase of the gold‐catalyzed phenol synthesis, the ring opening of the intermediate
arene oxide, follows general acid catalysis. The product selectivity is determined by the …

This Glossary contains definitions, explanatory notes, and sources for terms used in physical
organic chemistry. Its aim is to provide guidance on the terminology of physical organic …

Publisher Summary This chapter describes a method and its applications to chemical problems,
which are based on a combination of equilibrium isotope effects and nmr spectroscopy. …

Intramolecular addition of transient silylium ions 1 to C≡C bonds provides access to vinyl
cations 2 (see scheme; R=Me, Ph) which are remarkably stable at room temperature. The …

The mammalian target of rapamycin (mTOR) is a key regulator of cell growth and its uncontrolled
activation is a hallmark of cancer. Moreover, mTOR activation has been implicated in …

Evidently a σ complex and not a free uncomplexed silyl cation is present in the crystals of 1·
toluene. This follows from ab initio studies into the structure of the cationic complexes [Me 3 …

Atempts to ionize 11 and l-mesityl-2-(trimethylsilyl) alkyne (11, R= SiMe3) to yield the cations
1 and l-SiMe3 lead only to complex mixtures. 1 is formed, however, in a clean reaction, …

A series of N‐4‐(4′‐alkoxybiphenyl)‐N′,N′,N”,N“‐tetramethylguanidinium salts was
synthesized with varying alkoxy chain lengths and additional N‐alkyl substituents, each with a …

The l-(p-anisyl)-2-(triisopropylsilyl) vinyl cation 1 and the l-(p-anisyl) vinyl cation 2 were
generated in solution and characterized by NMR spectroscopy. Ab initio molecular orbital …

The source of conspicuous disagreement between theory and experiment for the chemical
shift of C α in the 1-cyclopropylcyclopropylidenemethyl cation is identified as an inadequate …
