organo‐lithium compoundsorgano‐potassium compounds1-Butene, cis/ trans-2-butene and 2-methylpropene were polymetalated by treatment with the product obtained by combination of n-butyllithium and potassium t-amyloxide. Polymetalation was determined by quenching with deuterium oxide and analysis by ...
supporting the proposal to employ the ether in pharmaceutical medicaments, PVP-iodine complexes, soaps and scrubs, binders of various sorts, glue sticks, hot melts, batteries, inks, photoresists, metal quenching compounds, membranes, and anti-recrystallization agents to name a few. The ...
The amide proton likely participates in the major quenching pathway. Acridones and acridines were synthesized by this aryne insertion, followed by an in situ SNAr reaction or Friedel-Crafts acylation (Fig. 2.2.9). The imide derivatives also undergo the aryne insertion reaction, which selectively ...
Light absorption excites complex (I) to its singlet state (I–S1), followed by the intersystem crossing (ISC) to generate the triplet state (I–T1) at the C=N bond, based on quenching experiments. A key step follows through a minimal energy crossing point (MECP) for the structural ...
to determine the prevailing radical species formed in the PMS/Co@N-PCNC systems, quenching investigations were executed employing the same procedure for the degradation experiment, only adding 1000 mM methanol (MeOH) or 1000 mM tertbutyl alcohol (TBA), as the scavenging agents,to the reaction ...
After addition is completed, the reaction temperature is allowed to warm to −20° and then is stirred for approximately 12 h before quenching with 20% aq ammonium chloride solution. The reaction is extracted with ethyl acetate and then worked up in a typical manner using a drying agent ...
Several techniques, such as grinding the radiation sensitive compositions into very fine particles and crystallizing into very fine particles by techniques such as rapid quenching can be used to provide the required transparency. A transparent radiation sensitive shaped-article will provide a clear image...
The deprotonation reaction of 3,6-di-tert-butyl-3H-azepine, (2), using methyllithium, and subsequent quenching of the resulting anionic species with acetyl chloride gave the title compound, C30H48N2O, (4) The structure of (4) consists of a boat-shaped 3H-azepine ring and an envelope-...
Quenching with tert-butyl nitroso 2-lithio-4-tert-butyl toluene prepared by an exchange reaction with t-butyl-lithium, followed by acidic hydrolysis furnishes in good yields the corresponding aromatic hydroxylamine whose oxidation affords the nitroxide, N-(2-methyl-5-tert-butyl-phenyl)-N-tert-...
