3-fluoropyridine were converted into all possible regioisomers of the corresponding carboxylic acids by passing through the corresponding organometallic intermediates. As an attempt to generalize the findings reveals, a restricted set of principles and methods suffices to cope with all std. scenarios. The most valuable and versatile tools for the regiochem. exhaustive functionalization of a great variety
在模型研究中,3-氟苯酚和 3-氟吡啶通过相应的有机金属中间体转化为相应羧酸的所有可能的区域异构体。正如对调查结果进行概括的尝试所揭示的那样,一套有限的原则和方法足以应对所有性病。场景。用于区域化学的最有价值和通用的工具。多种底物模式的详尽功能化是可选的位点选择性金属化(通过试剂/底物匹配或外围配位控制),使用激活或拥塞保护基团和碱性梯度驱动的重卤素迁移(随后是卤素/金属排列)。[在 SciFinder (R) 上]
