Fig. 8. Preparative electrospray of a base-catalyzed Claisen–Schmidt condensation of 1-indanone and 4-chlorobenzaldehyde. Top: Setup for synthesis using an array of four multiplexed ESSI sprayer tips (scheme, polypropylene vessel bottom sealed with glass wool and silica material, array of four ESSI sprayer tips). A solution of 0.83 mg of 1-indanone, 0.88 mg of 4-chlorobenzaldehyde and catalytic amounts of KOH was electrosprayed within 2.5 min and gave 1.47±0.09 mg or 92.2% of the main product. Bottom: Reaction scheme. Adapted from ref. 70 with permission. © 2012 Wiley-VCH Verlag GmbH and Co. KGaA, Weinheim.
