摘要:由苯胺在液体so 2中的溴化速率常数确定的十一种取代衍生物的反应结构相关性,与在水中观测到的不同,表明该反应对取代基效应高度敏感(ρ= −7.1;ρ= −10.51).该结果归因于甲氧基的溶剂化,与邻位取代的衍生物(ρ=-8.86)相比,其降低了对位取代的共轭(ρ=-9.70 ).高度溶剂化的过渡态在反应坐标上与反应物相距甚远,在此状态下产生的正电荷几乎为1.

权利人:RHONE POULENC CHIMIE
摘要:A liquid conductive composition for electrolytic use, comprises a cobalt salt, a zinc salt, a polar aprotic solvent of said salts and a cobalt ligand. The liquid composition is used in a process for the preparation of an organozinc compound by electrolytic synthesis. The process comprises the step of subjecting to an electrolysis on an inert cathode the liquid composition comprising a cobalt salt, a zinc salt, a solvent, a cobalt ligand, and an organic halide, and recovering the organozinc obtained by the electrolysis.
