Similarly, S-S metathesis was slow in diethylamine, requiring 24 hours to reach equilibrium. In contrast, n-butylamine promoted S-S exchange in minutes, but many other products also formed, including di-and tetrasulfide products. Together these results suggest that the rapid reaction and exclusive formation of trisulfides in the Category 1 solvents is not simply due to solvent nucleophilicity or contaminant amines.
