[email protected] Dr. S. J. Firsan With this issue of the Aldrichimica Acta, we are pleased to “I really like the Aldrichimica Acta papers. What is special about introduce our readers to the fresh and vibrant new look of them is that they are not only excellent reviews but also typically this venerable journal they have come to value and love. This describe chemistry that can be reproduced, upscaled, and done look weds the traditional successful elements of the Acta with with commercially available reagents and catalysts.” the design principles of the Acta’s new owner, Merck KGaA, — Professor Dr. Benjamin List (Max-Planck-Institut Darmstadt, Germany. This makeover couldn’t have come at a für Kohlenforschung) better time, as we are celebrating the Aldrichimica Acta’s golden “The combination of first hand accounts of scope and limitations jubilee year. While this look is new, I’m happy to assure our and commercially available reagents makes each account contributors and readers that the Acta’s aim will remain the published in Aldrichimica Acta the go-to guide for any chemistry.
