Cyclopentadienone is an organic compound with molecular formula C 5 H 4 O. The parent cyclopentadienone is rarely encountered, because it rapidly dimerizes. [1] Many substituted derivatives are known, notably tetraphenylcyclopentadienone. Such compounds are used as ligands in organometallic chemistry. [2]

The Rh (I)-catalyzed [3 + 2] cycloaddition of cyclopropenones and alkynes provides a highly efficient and regioselective route to cyclopentadienones (CPDs) that would be otherwise difficult to obtain. The versatility of the method is explored with a wide range of alkynes and diaryl- as well as arylalkylcyclopropenones.
