Using Taguchi Robust Design Method to Develop an Optimized Synthesis Procedure for Nanocrystals of ZSM‐5 Zeolite

A Taguchi orthogonal experimental design with three levels of the above?mentioned parameters was used to optimize the experiment parameters by the analysis of variances (ANOVA). Applying the Taguchi method significantly reduced the time and cost for optimization.

Direct Synthesis of Water‐Tolerant Alkyl Indium Reagents and Their Application in Palladium‐Catalyzed Couplings with Aryl Halides

A direct result: Alkyl indium reagents are synthesized by the insertion of indium into alkyl halide mediated by CuCl. The synthetic utility of these reagents is demonstrated by their palladium?catalyzed coupling with aryl halides (see scheme).
