Acid Chlorides as Formal Carbon Dianion Linchpin Reagents in the Aluminum Chloride-Mediated Dieckmann Cyclization of Dicarboxylic Acids

The development of acid chlorides as formal dianion linchpin reagents that enable access to cyclic 2-alkyl- and 2-acyl-1,3-alkanediones from dicarboxylic acids is described herein. Mechanistic experiments relying on 13C-labeling studies confirm the role of acid chlorides as carbon dianion linchpin reagents and have led to a revised reaction mechanism for the aluminum(III)-mediated Dieckmann cyclization of dicarboxylic acids with acid chlorides.

A prototype device for evaporation in batch and flow chemical processes

We report a convenient and efficient prototype device for evaporating, concentrating and switching solvents in continuous flow and batch processing and batch mode fashion. One of the main features of this system is the level of recyclability, whereby all solvents removed can be easily collected and reused, with reduced environmental impact.
