Author(s):   Ramalho, S.S.; Vilela, A.FA.; Barreto, P.RP.; Gargano, R.
Title:   Theoretical rate constants for the reaction BF2+NF=BF3+N of importance in boron nitride chemistry
Journal:   Chem. Phys. Lett.
Volume:   413
Page(s):   151 - 156
Year:   2005
Reference type:   Journal article
Squib:   2005RAM/VIL151-156

Reaction:   BF2 + NFBF3 + N
Reaction order:   2
Temperature:   200 - 4000 K
Rate expression:   4.34x10-15 [cm3/molecule s] (T/298 K)2.50 e207351 [J/mole]/RT
Category:  Theory
Data type:   Transition state theory
Comments:   Geometric parameters optimized at MP2/6-31G(d) level of theory. Electronic energies are from calculations at the QCISD(t)/6-311++G(d,p) level, where the calculated heat of reaction was closest to the literature value.

The first step in the reaction is a reversible formation of a complex, followed by an irreversible step.
