Abstract:
A number of alkali organometallic complexes with suitable thermodynamic properties and high capacity for hydrogen storage have been synthesized; however, few transition metal–organic complexes have been reported for hydrogen storage. Moreover, the synthetic processes of these transition metal–organic complexes via metathesis were not well characterized previously, leading to a lack of understanding of the metathesis reaction. In the present study, yttrium phenoxide and lanthanum phenoxide were synthesized via metathesis of sodium phenoxide with YCl3 and LaCl3, respectively. Quasi in situ NMR,

Abstract:
It was shown that selected sodium phenoxide derivatives with different basicity and nucleophilicity, such as sodium p-nitrophenoxide, p-chlorophenoxide, 1-napthoxide, phenoxide and p-methoxyphenoxide, are effective initiators in anionic ring-opening polymerization (AROP) of β-butyrolactone in mild conditions. It was found that phenoxides as initiators in anionic ring-opening polymerization of β-butyrolactone behave as strong nucleophiles, or weak nucleophiles, as well as Brønsted bases.

Abstract:
The effect of ion-pairing in an SN2 reaction is very different when the nucleophilic atom is changed from sulfur to oxygen, i.e., changing the nucleophile from thiophenoxide ion to phenoxide ion. When the nucleophile is sodium thiophenoxide, ion-pairing markedly alters the secondary α -deuterium kinetic isotope effect (transition state structure) and the substituent effect found by changing the para substituent on the nucleophile. When the nucleophile is sodium phenoxide, ion-pairing does not significantly affect the secondary α -deuterium or the chlorine leaving group kinetic isotope effects

Problems of competitive attack by this nucleophile, at the less substituted carbon (compounds A) or at the β-ethylenic carbon atom (compounds B and C), were encountered and could be resolved by judicious choice of reaction conditions (solvents, stereochemistry of the oxiranes). The regioselectivity of the attack was dependent on the transition states, implying weak steric hindrance and a conjugation oxirane – double bond.

Abstract:
Polymers of styrene of various type can be readily amidomethylated by a reaction with N-(hydroxymethyl)amides. Analogs of N-methyl-2-pyrrolidone, N-methyl-6-hexanelactam, N-methyl-8-octanelactam, and N,N-dimethylacetamide were prepared by the polymeranalogous amidomethylation. The reaction between poly(styrene-co-divinylbenzene) and N-(hydroxymethyl)-2-pyrrolidone proceeds by an acceleration mechanism. The extent of the reaction depends on the structure of the polymer and N-(hydroxymethylamide), on the concentration of the catalyst (trifluoroacetic acid) and on the way in which the polymer swe

Abstract:
The purpose of this communication is to clear up what is happening in the test tube during the interaction of an alkaline solution of morphine with Lugol’s iodine (Kippenberger test for morphine). The formation mode and reactivity of potassium triiodide, the salt present in Lugol’s solution, are commented. Reaction of iodine molecule (formed in a reversible manner) with sodium hydroxide gives rise to hypo-iodous acid. This reacts with the morphine phenolate formed in situ yielding an organic hypoiodite. This labile intermediate loses iodide ion, producing a ketone and Umpolung at the ortho-pos

Abstract:
Carboxylation reactions using carbon dioxide (CO2) as a reactant to produce new C-C bonds represent one of the most promising routes in carbon capture and utilization practices, which yield higher-atom and energy-efficient products. Kolbe–Schmitt-type reactions represent the carboxylation of aromatic compounds to their carboxylic acid derivatives. This study was the first and only to systematically investigate, thoroughly explain preparation procedures, and minutely describe the analytical methods of Kolbe–Schmitt and Marasse carboxylation of phenol. Most importantly, this study provides guide

Sodium and potassium phenoxide, in the presence of one equivalent of dicyclohexano-18-crown-6 (cis–anti–cis isomer) and dibenzo-18-crown-6, form complexes that have a ratio of 1:1:1 (crown:salt:phenol) in ethereal solvents containing excess phenol. On the other hand, complexes having 1:1:2 ratios (crown:salt:phenol) are obtained under the same conditions when the macrocycle is 18-crown-6 or dicyclohexano-18-crown-6 (cis–syn–cis isomer). When only one equivalent of phenol is present, then 1:1:1 complexes are obtained with 18-crown-6 and dicyclohexano- 18-crown-6 (cis–syn–cis isomer). No complex

Abstract:
Anisole is a straw-colored aromatic compound mainly used in making solvents, flavoring agents, perfumes, fuel additives, and in the synthesis industries. Anisole, also known as methoxybenzene, is synthesized from sodium phenoxide or phenol using various methylating agents. The use of dimethyl ether (DME) as an alkylating agent is seldom reported in the literature. Herein, we have synthesized anisole through the O-alkylation process of phenol and DME to obtain zero discharge from this process. The thermodynamic equilibrium for the reaction of phenol and DME is simulated by using Aspen HYSYS (Hy
