the adamantane series in the system H2SO4–HNO3 have been studied, and the effective rate constants have been determined. The reaction is described by the pseudo-first-order kinetic equation. The primary kinetic isotope effect has been estimated at 2.9±0.3. The rate-determining step of the oxidation process is cleavage of the adamantane C–H bond. The presence of an ethyl group at the bridgehead position
摘要研究了H 2 SO 4 -HNO 3体系中16种金刚烷系列羧酸酯的氧化动力学 ,并确定了有效的速率常数。该反应由拟一级动力学方程式描述。初步的动力学同位素效应估计为2.9±0.3。氧化过程的决定速率的步骤是金刚烷CH键的断裂。在桥头位置存在乙基会增加金刚烷底物对氧化的反应性,而甲基,乙氧羰基和乙氧羰基甲基会降低反应性。
