Calcium‐Mechanochemistry Enabled Ketone Synthesis From Organic Iodides and Carboxylic Acids
Advanced Science, EarlyView.Mechanochemically generated organocalcium species display unusual chemoselectivity toward carboxylates, enabling direct ketone synthesis without overaddition. Ball milling activates commercial calcium metal under ambient, solvent‐minimized conditions, providing a broad substrate scope, high functional‐group tolerance, and a practical one‐step ...

Stainless steel is rapidly achieving pre‐eminence as a favoured material of construction due, no doubt, to the fact that for many applications in chemical plant it is the only material that can fulfil the stringent requirements as well as ensuring minimum maintenance costs. This article describes the constitution of stainless steels and their physical,
