Abstract

The reactivities of tantalum oxide cluster cations with unsaturated hydrocarbons have been probed using a triple quadrupole mass spectrometer coupled with a laser vaporization source. The reaction pathways observed for the tantalum oxide clusters with 1,3-butadiene (C4H6), 1-butene (C4H8), and (D6)benzene (C6D6) include association, atomic and molecular oxygen loss, cracking, minor dehydration, and possible dehydrogenation with the reactivities of different clusters varying from species to species. In the case of 1,3-butadiene, the major reaction product involves cracking of the C2-C3 bond to give TaxOy- (C2H4) reaction channels. The major reaction of tantalum oxide clusters with 1-butene is again cracking of the C2-C3 bond to give TaxOy+(C2H4) reaction products. Lastly, cracking of the stable benzene ring to give TaxOy-(C4D4) is the major reaction pathway for tantalum oxide clusters interacting with (D6) benzene. (Int J Mass Spectrom 184 (1999) 119-128)
