effect of high pressure is examined in Strecker reactions involving ketones, amines and trimethylsilyl cyanide. This effect is small when moderately hindered reactants are involved. However, in the case of aniline and N-methylaniline, the sensitivity of the reaction to pressure increases with increasing steric bulk of the alkyl groups of the ketone. The results confirm the merit of pressure activation
在涉及酮,胺和三甲基甲硅烷基氰化物的斯特雷克反应中检查了高压的影响。当涉及中度受阻的反应物时,这种作用很小。然而,在苯胺和N-甲基苯胺的情况下,反应对压力的敏感性随酮烷基的空间体积增加而增加。结果证实了压力激活的优点,因为空间要求较高的反应比其不受阻碍的类似物具有更高的压力加速度。
