Procedure

Benzyl bromide was reacted with the ammonium salt of dicyclohexylphosphinodithioic acid to obtain benzyl dicyclohexylphosphinodithioate, m.p. 107°14 108° C, which on testing lasted 350 hours longer than the control. The total number of hours required to reach failure was 1.9 times that of the control.
