Self-sustaining reactions induced by ball milling

If this hypothesis is valid ignition is controlled by different criteria in the cases of Zn and Sn. One possibility is the following when Zn is processed with S in the ball mill the decisive process is the initiation of a primary reaction. Once that happens the reaction front propagates through the vial easily due to the large self-heating.

Synthesis of mono-functionalized S-diazocines via

pling with lead 17 . In this reaction a small amount of S-diazocine is directly formed and a larger fraction of the azoxy compound is obtained which can be reduced in a second syn-thetic step using lead in a ball mill. However these reaction conditions are not suitable for functionalized S-diazocines due to poor yields and low reproducibility.
