It must be realized that the basic reason for bifurcation is that the function F is multiple-valued and therefore non-linear. Other sources of non-linearity, like auto-catalysis have been explored systematically and have proven to be the starting point of geochemical catastrophes (e.g., Ortoleva, 1994).

Both 2-methyl- and 4-methyl-quinolizinium salts undergo the Ortoleva-King reaction (Scheme 37) to produce the expected pyridinium salts and these with p-dialkylamino-nitrosobenzenes were found to give nitrones (46) (65JPR(27)306).
