Diazocyclopentadiene (1) was photolyzed in N(2), CO, and other low-temperaturematrices. The resulting carbene, cyclopentadienylidene (2), was characterized by its UV and IR spectra, and its thermaldimerization and reaction with CO were observed. Photolysis of 1 with plane-polarized light gave matrices exhibiting linear dichroism. Comparison of dichroic IR and UV spectra revealed that the photolysis

Fluoride anion promoted dehalosilation of 2-(chlorocyclopropyl)trimethylsilanes in the gas-phase was used to prepare a variety of monosubstituted cyclopropenes containing additional unsaturations. The cyclopropylsilanes were constructed easily from common intermediates.
