(a) The values found in the literature for the bond angle C(2)C(1)C(4) in monocyclic cyclobutanones, which are taken from X‐ray structural determinations, vary between 90.4 [218a] and 93.5° [7f]. The corresponding angle in the unsubstituted cyclobutanone was determined by microwave spectroscopy to be 93.1 ± 0.3° [218b]. ‐
