The Koenigs and Knorr reaction , discovered at the turn of the 19th century, is illustrated in the cover art; the old car on the left illustrates that the reaction is very slow in the presence of silver(I) oxide. This work reports that this reaction can be significantly accelerated by the addition of catalytic triflic acid, which is illustrated by the fast sports car on the right. The progress and the completion of the reaction can be judged by the color change. Go, get‐ready, and stop stages of the reaction are symbolized with the traffic light.
