to measure the absolute bimolecular rateconstants for hydrogenatomabstraction in water from a series of fluorinated alkoxides and aldehyde hydrates by the perfluoroalkyl radical, *CF2CF2OCF2CF2SO3- Na+. The bimolecular rateconstants observed for the beta-fluorinated alkoxides were in the 10(5) M(-1) s(-1) range, such rates representing enhancements (relative to the respective alcohols) of between
激光闪光光解法和竞争动力学方法相结合已用于测量全氟烷基自由基* CF2CF2OCF2CF2SO3- Na +从一系列氟化的醇盐和醛水合物中提取氢原子的绝对双分子速率常数。β-氟化醇盐的双分子速率常数在10(5)M(-1)s(-1)范围内,这种速率代表100到几乎1000倍之间的增强(相对于相应的醇),取决于醇盐的反应性。同样,相对于它们各自的水合物,氯醛和氟代水合物的一元钠盐显示出相似的速率增加。

Formal Cu(III) complexes bearing an oxygen-based auxiliary ligand ([CuOR]2+, R = H or CH2CF3) were stabilized by modulating the donor character of supporting ligand LY (LY = 4-Y, N,N′-bis(2,6-diisopropylphenyl)-2,6-pyridinedicarboxamide, Y = H or OMe) and/or the basicity of the auxiliary ligand, enabling the first characterization of these typically highly reactive cores by NMR spectroscopy and X-ray
通过调节支持配体 L Y ( L Y = 4 - Y , N , N '-双(2,6-二异丙基苯基)-2,6-吡啶二甲酰胺, Y = H 或 OMe) 和/或辅助配体的碱度, 能够通过 NMR 光谱和 X 首次表征这些典型的高反应性核- 射线晶体学。观察到苯酚底物在溶液中的寿命延长和 PCET 速率降低。核磁共振光谱证实了S= 0 配合物的基态,X 射线结构显示缩短的 Cu-配体键距离与理论非常吻合。
Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonamides, e.g., 5,7-dimethyl-N-(2,6-dichlorophenyl)-1,2,4-triazolo[1,5-a]pyrimidine-2-sulf onamide and their agriculturally acceptable salts are prepared. These compounds and compositions containing them are useful for the control of unwanted vegetation. Novel substituted triazolo[1,5-a]pyrimidine-2-sulfonyl chlorides and substituted anilines and their use as intermediates are also described.
