Abstract
Abstract The highly strained and reactive dimethylenebicyclo[1.1.1]pentanone (I), was prepared as follows. Treatment of 1,5-bis(chloromethyl)tricyclo[2.1.0.0 2, 5 ]pentan-3-one diethyl ketal (III) with di-t-butyl hydrazodicarboxylate (VII), followed by pyridinium p-toluenesulfonate and trifluoroacetic acid, yielded the keto hydrazine X which was oxidized to the desired ketone I. The ketone I decomposes very rapidly above −30°C.
