Cyclopentadienone (1) can be generated by photolysis or pyrolysis of several precursors and isolated in an argon matrix.It dimerizes even on thawing of the matrix (38 K).The IR and UV spectroscopic properties of 1 are discussed.

New routes to cyclobutadiene (2) and methylenecyclopropene (4) are described.Matrix irradiation of cyclopropenylketene (9) gives cyclobutadiene.Flash pyrolysis of 8, 11, 16, 17 and 18 also generates cyclobutadiene, which can be deposited from the gas phase onto a window cooled to 10 K.Methylenecyclopropene is one of he products in the thermal fragmentation of 8 or 14.
