The most general pathway for the decomposition of the molecular ions of 4,4-disubstituted 1-alkylidene-2,5-cyclohexadienes is the loss of the substituent at the geminal unit. The facility of this process is a function of the stability of the group eliminated. The formation of cationic rhodium complexes containing alkylidenecyclohexadiene and alkylidenecyclohexadienyl ligands is possible in the gas phase as a result of intramolecular dissociation and ion-molecule reactions. The formation of cationic complexes also occurs as a result of the reaction of benzene derivatives with acacRh(CO)/sup +//sub n/ ions. The donor capacity of 4,4-disubstituted 1-alkylidene-2,5-cyclohexadienes in reactions with acacRh(CO)/sup +//sub n/ ions is comparable with the donor capacity of their aromatic isomers.
