The allylic hydrogen is found to have a dramatic effect on the
regioselectivity of the Wacker oxidation, leading to the postulation that
an agostic hydrogen or enyl (σ + π) complex helps to stabilise the
key intermediate.

α‐Arylketones are both structure moieties commonly found in bioactive compounds and versatile synthetic intermediates for the preparation of drug‐like molecules. An operationally simple and scalable protocol has been developed to prepare α‐arylketonesfrom readily available aromatic amines and enolacetates (or silyl enol ethers). This metal‐free methodology features the use of salicylic acid as

We report a transition-metal-free coupling of aldehydes and ketones with geminal bis(boron) building blocks which provides the coupled, homologated carbonyl compound upon oxidation. This reaction not only extends an alkyl chain containing a carbonyl group, it also simultaneously introduces a new carbonyl substituent. We demonstrate that enantiopure aldehydes with an enolizable stereogenic center undergo
Ring size and nothing else matters: unusual regioselectivity of alkyne hydration by NHC gold(<scp>i</scp>) complexes

We have investigated the role of ring sizes and substituents in NHC ligands in some (NHC)Au(I) complexes in the hydration of internal alkynes. Despite the fact that using (NHC)Au(I) complexes in the hydration of diarylacetylenes leads to Markovnikov-type products, the precise tuning of ligands allows changing the regioselectivity in arylalkylacetylene hydration to the anti-Markovnikov-type.
