A selective electrochemical oxidation was developed under mild condition. Various mono-carbonyl and multi-carbonyl compounds can be prepared from different aromatic hydrocarbons with moderate to excellent yield and selectivity by virtue of this electrochemical oxidation. The produced carbonyl compounds can be further transformed into α-ketoamides, homoallylic alcohols and oximes in a one-pot reaction

The invention concerns quinuclidine derivatives of formula I or II wherein the substituents are as defined in the specification, as well as their use as pharmaceuticals. The compounds of the invention_show high affinities for m3 and/or m2 muscarinic receptors and are particularly suited for treating urinary incontinence.
investigations discovered that the generated phenylhydrazone anion was significantly bathochromically shifted to visible light region for photoactivation under irradiation. The photoexcited phenylhydrazone anion was potential to reduce aryl iodides single electron transfer process for the subsequent radical chain reaction. A redox-neutral photochemical carbonylation of aryl iodides was developed on basis of
