binary reaction sequences i(j,k)l where i, j, k, and l are distinct 
particles with stoichiometric coefficients of unity are handled
by the mechanism you are trying with relative ease.

when there are identical particles in the entrance or exit channels,
or the stoichiometric coefficient is not equal to one, mesa treats
them as special_case_reactions that need specific code (e.g., /net/private/net_initialize.f90).
examples include triple-alpha, c12(c12,alpha)ne20, and everyone's favorite 
big bang reaction sequence t(t,2n)he4. 

to add a sequence like 106cd(g,2n)104cd which has a stoichiometric coefficient 
of 2 in the exit channel will require custom coding. this said, if i have missed 
some magic in the code, i'm sure a mesa-developers will let me know i'm wrong!
