The two simplest unsaturated glyoxals 1 and 2 have been prepared by gasphase pyrolysis from 5‐norbornen‐2‐yl‐CO‐CO‐R, R5‐norbornen‐2‐yl and Me, respectively. The UV and PE spectra of the yellow diones 1 and 2 reveal a preferred conformation in which the carbonyl groups—in contrast to those in benzil—are arranged in a nearly antiperiplanar fashion.
