• Competing Fragmentation, Substitution and Elimination in the Solvolysis of Alkylated 3-Chloropropanols and their Ethers. Fragmentation reactions no. 28

  The unstrained 3-chloroalcohols 1a, 2a and 3a do not undergo solvolytic fragmentation in neutral and weakly acidic 80% ethanol, only substitution and elimination products being formed by the limiting SN1-E1 mechanisms. This also applies to the corresponding ethers 1b and 3b. Addition of sodium hydroxide causes the observed rate constants for the 3-chloroalcohols to rise steeply by factors of at least

  未应变3- chloroalcohols 1A，2A和3A中不发生在中性和弱酸性的80％乙醇溶剂化碎片，仅替代和消除产物由限制性形成小号Ñ 1 - E1的机制。这也适用于相应的醚1b和3b。加入氢氧化钠会使3-氯醇的观测到的速率常数急剧上升至少10 3至10 5倍。由于相反的离子强度效应，这些在较高的碱浓度下趋于稳定。而3a片段定量在碱的存在下1A和2A片段与消除竞争的Δ 3烯烃9A和10分别。2a还产生2％的氧杂环丁烷6b。
