Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system.

Author is Camasso, Nicole M.; Sanford, Melanie S..

Homogeneous nickel catalysis is used for the synthesis of pharmaceuticals, natural products, and polymers. These reactions generally proceed via nickel intermediates in the Ni0, NiI, NiII, and/or NiIII oxidation states. In contrast, NiIV intermediates are rarely accessible. Authors report herein the design, synthesis, and characterization of a series of organometallic NiIV complexes, accessed by the reaction of NiII precursors with the widely used oxidant S-(trifluoromethyl)dibenzothiophenium triflate. These NiIV complexes undergo highly selective carbon(sp3)-oxygen, carbon(sp3)-nitrogen, and carbon(sp3)-sulfur coupling reactions with exogenous nucleophiles. The observed reactivity has the potential for direct applications in the development of nickel-catalyzed carbon-heteroatom coupling reactions.

Compound: Potassiumtris(1-pyrazolyl)borohydride, is researched, Molecular C9H10BKN6, CAS is 18583-60-3, about Two-stage hybrid constructed wetland-microbial fuel cells for swine wastewater treatment and bioenergy generation. Author is Ren, Baiming; Wang, Tongyue; Zhao, Yaqian.

A newly emerged alum sludge-based hybrid constructed wetland-microbial fuel cells (CW-MFCs), i.e. vertical upflow CW coupled MFC as 1st stage and horizontal subsurface flow CW coupled MFC as 2nd stage (VFCW-MFC + HSSFCW-MFC), was firstly developed for swine wastewater treatment and electricity generation. Swine wastewater and multi-set air-cathodes were applied to investigate the pollutants removal behavior and the power production Six-month trial suggested that the overall removal efficiency of SS, COD, NH+4-N, NO-3-N, TN, TP and PO3-4-P was 76 ± 12.4, 72 ± 7.4, 59 ± 28.3, 69 ± 25.6, 47 ± 19.7, 85 ± 9.5 and 88 ± 8.7%, resp. The two stages hybrid system (VFCW-MFC + HSSFCW-MFC) continuously generated elec. power with average voltages of 0.44 ± 0.09 and 0.34 ± 0.09 V, and power densities of 33.3 ± 13.81 and 9.0 ± 2.5 mW/m3 in 1st and 2nd stage, resp. The average net energy recovery (NER) of 1st stage and 2nd stage is in turn 0.91 ± 0.16 and 2.76 ± 0.70 Wh/kg·COD. It indicates that the hybrid CW-MFCs has higher removal efficiency than single stage CW-MFC, while 1st stage plays the major role both in pollutants removal and power generation.
