The addition of proton acids as HF, HCl, HBr, HOAc and phenol to alkyne-derivatives of the type (CH3)2NCCCOR(1) yielding the adducts 2 to 6 is investigated. The stereochemical course of the reaction is mainly influenced by the structure of the alkyne 1. Kinetic investigations show that the rate of the third-order-reaction increases from 1 a (RH) to 1 b (R CH3) and 1 c (R OCH3) and decreases drastically
研究了质子酸如HF,HCl,HBr,HOAc和苯酚向(CH 3)2 NCCCOR(1)型炔烃衍生物的加成反应,生成加合物2至6。反应的立体化学过程主要受炔烃1的结构影响。动力学研究表明,在极性溶剂中,三级反应的速率从1a(RH)增至1b(R CH 3)和1c(R OCH 3),并显着降低。根据这些结果,概述并讨论了反应机理。
