We wish to record the thermolysis of homophthalic anhydride (L), a process which provides a ready synthesis of either bensocyclobutenone (2) or fulveneallene (3). Pyrolysis at two mm by subliming 1 (2.7-3.0 g during a period of 1-2.5 hr) in a stresm of nitrogen (22 ml/min at 690 mm) over a hot nichr
## Abstract An NMR study of ketones 5โ12 was undertaken to gain insight into the low electrophilicity of the carbonyl moiety of butenones 9โ11. Initial IR studies on compounds 9โ12 indicated that there is relatively strong double bond character (and hence low electrophilicity) in the carbonyl of sa
