Front Cover: A Strategy for the Simultaneous Synthesis of Methallyl Alcohol and Diethyl Acetal with Sn‐β (ChemSusChem 23/2017). Issue 23 (8th December 2017) - Hu, Wenda
Abstract : The Front Cover shows a strategy to simultaneously produce two important chemicals, namely, methallyl alcohol and diethyl acetal. They are produced from methacrolein in ethanol solvent at low temperature on Beta zeolites modified by tin (Sn‐β catalysts). The catalyst pre‐calcined in Ar (Sn‐β‐Ar) enables more Sn species to be exchanged into the framework as isolated tetrahedral Sn(IV), thus enhancing the catalytic activity of the Meerwein–Ponndorf–Verley reaction. The findings of Sn‐β fine‐tuned through different treatments are of great significance toward understanding and manipulating the complex reaction between α, β‐unsaturated aldehydes and primary alcohols.
