Relative Ease of Formation of Alkylidine(oxo and thioxo)phosphorane Intermediates in Nucleophilic Substitution at Phosphonyl and Thiophosphonyl Centres

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.

Relative Ease of Formation of Alkylidine(oxo and thioxo)phosphorane Intermediates in Nucleophilic Substitution at Phosphonyl and Thiophosphonyl Centres

Abstract: The conversion of R 2 CHP(X)(NEt 2 )Cl (R 2 CH 9-fluorenyl) into R 2 CHP(X)(NEt 2 ) 2 via the intermediate R 2 C.P(X)NEt 2 (elimination±addition mechanism) is much faster when X S than when X O.
