He(I) PE spectra of a series of 3,3-dimethylcyclopropenes bearing Me3Si (1), Me3Ge (2), and Me3Sn (3) groups in the 1- and 2-positions, as well as the He(II) PE spectra of 1 and 3 were recorded. The changes in the lowest energy ionizations along the series are interpreted in terms of inductive and hyperconjugative interactions. The new compounds were prepared by reaction of lithiated 3,3-dimethylcyclopropene with the corresponding trirnethyimetal chlorides. VCH Verlagsgeseiischaft mbH 1996.
New functionalized 3,3-dimethylcyclopropene derivatives and their rearrangement via vinylcarbene intermediates

The 1-(methylthio)-substituted cyclopropenes 5a-c and the corresponding tert-butyl 1-cyclopropenecarboxylate 10, which are easily prepared by electrophilic substitution of the protected monolithiated 3,3-dimethylcyclopropenes 3a-c, are reasonable stable at room temperature.Upon heating to 150 deg C, or under photolytic conditions, both 5a and 10 form allenes 8 and 11, exclusively.The first-order kinetics of the rearrangement 3a -> 8 was determined as ln(k) = 27.54-28040/(R*T).
