Pirzer, Anna S.; Alvarez, Eva-Maria; Friedrich, Heike; Heinrich, Markus R. published an article in 2019, the title of the article was Radical Carbofluorination of Alkenes with Arylhydrazines and Selectfluor: Additives, Mechanistic Pathways, and Polar Effects.Formula: C7H7FO And the article contains the following content:

Radical carbofluorination reactions starting from arylhydrazines and nonactivated alkenes, in which the C-F bond is formed through the use of Selectfluor, can be improved through the addition of anisole. Because direct trapping products could be detected only in trace amounts, anisole does primarily act as a reversible scavenger for the highly reactive ammonium radical dication released from Selectfluor in the C-F bond-forming step. As shown for three diverse substitution patterns, the main role of anisole is to prevent, or at least reduce, the undesired addition of the ammonium radical dication to the alkene, which in turn leads to an unfavorable consumption of the arylhydrazine-derived precursors required for carbofluorination. Moreover, besides the remarkable polar effects in radical trapping, this study shows that the Selectfluor-derived nitrogen-centered radical dication may add directly to alkenes, which has not been described so far. The experimental process involved the reaction of 1-Fluoro-2-methoxybenzene(cas: 321-28-8).Formula: C7H7FO

Capozzi, Maria Annunziata M.; Centrone, Caterina; Fracchiolla, Giuseppe; Naso, Francesco; Cardellicchio, Cosimo published an article in 2011, the title of the article was A Study of Factors Affecting Enantioselectivity in the Oxidation of Aryl Benzyl Sulfides in the Presence of Chiral Titanium Catalysts.Name: Benzyl(4-bromophenyl)sulfane And the article contains the following content:

A series of experiments was performed to test a theor. model that we have recently proposed to explain the highly enantioselective oxidation of aryl benzyl sulfides with tert-Bu hydroperoxide in the presence of a complex between titanium and (S,S)- or (R,R)-hydrobenzoin. The studied variations involved the sulfides, the ligands, and the order of addition of reactants. The reaction path predicted by our model was confirmed in every experiment In particular, aryl benzyl sulfides behaved as the ideal substrate for this type of asym. oxidation, which yields synthetically useful, enantiopure aryl benzyl sulfoxides in a straightforward manner. The experimental process involved the reaction of Benzyl(4-bromophenyl)sulfane(cas: 53136-21-3).Name: Benzyl(4-bromophenyl)sulfane
