Abstract

The formation of Ni(II)–Leucine (Leu) complex (1:1) is established. It acts as a model homogeneous catalyst on the decay of cumene hydroperoxide (ROOH) in the studied system H2O–Ni2+–Leu–ROOH. ROOH catalytic decay rate law is: W0 = –d [ROOH]0/dt=Kcat [Ni2+Leu]0[ROOH]0=Keff[ROOH]0. The temperature dependence of ROOH decay rate effective constant Keff (Keff=Kcat[Ni2+Leu]0=const) in the 50–700C temperature range can be expressed by Arrhenius equation (the activation energy is expressed in kJ/mol): Keff = (1.87 ± 0.02)105 exp[(–46.6 ± 0.20)/RT], min–1.
