Fe(Pc)-Catalyzed aerobic oxidation of thiols for the synthesis of disulfides has been developed under mild reaction conditions. In addition, an aerobic oxidative cross-dehydrogenative coupling (CDC) reaction of thiols with P(O)-H compounds (H-phosphonates and H-phosphine oxide) for the formation of S-P(O) bonds has been demonstrated under the Fe(Pc) catalysis system with a base additive. Control experiments revealed that the use of a base (DIPA) in this system controls the synthetic pathways in which thiophosphates are formed.
A metal-, toxic chloride reagent-free activating strategy of various phosphates has been developed. This method enables the facile synthesis of functional phosphates such as alkyl phosphates, aza phosphates, thiophosphate, and mixed diaryl phosphates. A transient phosphorylpyridin-1-ium species in situ generated from phosphates with TfO/pyridine readily undergoes a substitution reaction with diverse nucleophiles to form versatile phosphate compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
