The rhodium(III)-catalyzed aryl borrowing amination of various diaryl methanols with sulfonamides have been developed. The amination of alcohols via C−C bond activation is less developed and remains a challenge. These aryl borrowing reactions feature mild reaction conditions, good functional group tolerance, and compatibility with a wide range of alcohols, overall comprising an atom- and step-economic

A silver catalyzed pyridine‐directed acceptorless dehydrogenation of secondary benzyl alcohols was developed. This general procedure delivers ketones with high atom‐economy and hydrogen was the sole byproduct. This dehydrogenation reaction has a good functional group tolerance and high efficiency (up to 90% yield and 10,000/1 substrates‐to‐catalyst ratio).
