A convergent, catalytic asymmetric formal [4 + 2] annulation for the synthesis of dihydroquinolones has been developed. Carboxylic acids can be employed as precursors to NHC enolates through an in situ activation strategy. Simultaneous generation a reactive aza-o-quinone methide under basic conditions leads dual approach.
Abstract Katalytische Umwandlungen mit N‐heterocyclischen Carbenen (NHCs) haben sich als effiziente Ansätze zum Aufbau komplexer Moleküle erwiesen. Seit der Veröffentlichung von Stetter 1975 zur Totalsynthese cis‐Jasmon und Dihydrojasmon durch Carbenkatalyse hat die Anwendung NHCs in Totalsynthese, insbesondere den letzten zehn Jahren, schnell verbreitet. Dieser Aufschwung ist zweifellos Folge neuerer Entwicklungen bei NHC‐katalysierten Reaktionen, einschließlich neuen Benzoin‐, Stetter‐,...
Sebacate (SB) molecules were incorporated into CaAl layered double hydroxides (CaAL-LDH) using a hydrothermal method. The resulting products underwent characterization through X-ray diffraction, infrared spectroscopy, and scanning electron microscopy. To investigate the release kinetics thermodynamics of corrosion inhibitor, total organic carbon analysis (TOC) was employed. A comparison made with CaAl-LDH prepared without inhibitors, in which nitrates primary anions within clay structure. An...
The fabrication of a solid-contact, micropipette-based magnesium ion-selective micro-tipped electrode (ISME) suitable for scanning electrochemical microscopy is reported and compared against conventional ISME having aqueous internal reference electrode. Measurements showed that the solid-contact had lower resistance faster response time than one with liquid-contact. These advantages increased spatial distribution improved 2D images depicting concentration distributions Mg2+. ability...
Magnesium (Mg) and its alloys undergo corrosion at high rates in aqueous electrolytes of essentially any concentration, releasing copious amounts hydrogen (H2) into the electrolyte, thereby making conventional scanning electrochemical microscopy (SECM) measurements difficult upon Mg. Examples issues associated with Mg SECM, strategies to counter these, are discussed this review. SECM has been employed Sample Generation-Tip Collection (SG-TC) mode image cathodic sites on surface, wherein,...
In situ localized electrochemical activity in the Al/Cu galvanic pair at corrosion potential an aggressive chloride electrolyte was investigated, along with effect of organic inhibitors 2-mercaptobenzimidazole (MBI) and octylphosphonic acid (OPA) on arresting corresponding processes. Scanning microscopy (SECM) scanning vibrating electrode technique (SVET) were used to discern local anodic cathodic sites surface. The greatly reduced when copper surface covered MBI-containing film. SECM...
A new approach to studying the mechanism of filiform corrosion in organic coated steel based on scanning vibrating electrode technique (SVET) and micropotentiometry (potentiometric SECM) is presented. The electrochemical activity process under coating evaluated by mapping ionic current densities emanating from some artificial defects made specific locations filament identifiable thanks transparency coating. In addition, antimony tips are employed investigate pH changes associated different...
