Ketones are a fundamental functionality found throughout a range of natural and synthetic compounds, making their synthesis essential throughout the chemical disciplines. Herein, we describe a one-pot synthesis of ketones via decatungstate-mediated formal dehydrogenative coupling between aldehydes and non-activated hydrocarbons. A variety of substituted benzaldehydes and cycloalkanes could be used

The present invention provides a method for producing a silicon compound shown by the following general formula (3) through a hydrosilylation reaction between a hydrosilane compound shown by the following general formula (1) and a carbonyl group-containing alicyclic olefin compound shown by the following general formula (2), in which the hydrosilylation reaction takes place while an acidic compound or acidic compound precursor is gradually added in presence of a platinum-based catalyst. This provides a highly-efficient industrial method for producing an industrially useful, hydrolysable silicon compound having an alicyclic structure (particularly a norbornane ring) and a carbonyl group.

its combined anticholinergic, antispasmodic, and local anesthetic activities. In a study directed toward development of agents possessing the beneficial properties of oxybutynin, but having a longer duration of action, a series of metabolically more stable keto analogues of the parent ester, i.e. substituted 7-amino-1-hydroxy-5-heptyn-2-ones along with some analogues and derivatives, was prepared and
