Angewandte Chemie International Edition, EarlyView.Geminal difunctionalization of readily available building blocks provides rapid access to molecular complexity. This work introduces a strategy for installing two distinct functional groups on a carbonyl carbon by transforming it into a donor–donor diazo compound, enabling both batch and flow applications with broad solvent compatibility.

Diarylmethyl Ethers for the Protection of Polyols
Journal of Chemistry, 2013 The paper discusses the use of diarylmethyl ethers for the protection of hydroxyl groups, in particular, carbohydrate hydroxyl groups. The formation of these ethers can be done nonselectively by the thermal reactions of diryldiazomethanes via a carbene ...
