Title:   Theoretical study of the reaction mechanism of abstraction reactions of disilenes and digermanes with haloalkanes
Journal:   J. Phys. Chem. A
Volume:   108
Page(s):   823 - 832
Year:   2004
Reference type:   Journal article
Squib:   2004SU823-832

Reaction:   (SiH3)2Si=Si(SiH3)2 + CCl4 → Other Products + ·CCl3
Reaction order:   2
Rate expression:   no rate data available
Category:  Uncategorized
Comments:   No rate constants reported. Just barrier heights and energetics of pathways. DFT quantum chemistry study of reaction between CCl4 and Disilene and Digermene species, e.g. SiH2=SiH2 and GeH2=GeH2 substituted with F, Cl, CH3, or SiH3. Used B3LYP/6-311G(d) method.

For reactions involvoing Si2(CH3)4 and Si2(SIH3)4, the calculations suggest no barrier and the heats of reactions being about -20 to -25 kcal/mol (exothermic).
