Title:   Competition between C-C and C-H activation in reactions of neutral yttrium atoms with four butene isomers
Journal:   J. Phys. Chem. A
Volume:   107
Page(s):   9295 - 9300
Year:   2003
Reference type:   Journal article
Squib:   2003SCH/WAN9295-9300

Reaction:   (E)-2-C4H8 + Y → Products
Rate expression:   no rate data available
Category:  Experiment
Data type:   Mechanistic information only
Experimental procedure:   Molecular beam
Comments:   The authors studied the reactions of neutral, ground-state Y (a2D, s2d1) with 1-butene, cis-2-butene, trans-2-butene, and isobutene using crossed molecular beams. Four processes were observed at collision energies of 26.6 kcal/mol for reactions with cis- and trans-2-butene and 1-butene. These were nonreactive scattering of yttrium atoms and formation of the respective products YC4H6 + H2, YH2 + C4H6, and YCH2 + C3H6. For the isobutene reaction, all channels but the YH2 product channel were observed. Formation of YC4H6 is always the dominant process.
