The gas phase ion molecule, reactions between carbon suboxide, neutral or r
adical cation, and different ionic or neutral substrates have been investig
ated or reviewed. The experiments show that neutral C3O2 is reactive with i
onized target, reflecting the high nucleophilicity of carbon suboxide. (Int
