“…To a stirred solution of hydridophosphorane 1 [9] (20 mmol) in 10 mL acetonitrile or dichloromethane were added tetrachloromethane (40 mmol), triethylamine (60 mmol), and the selected nucleophilic reagent (40 mmol) (dimethylamine was passed in as a gas) at room temperature. The reaction mixture was stirred at ambient temperature for several hours until the 3'P NMR signal of hydridophosphorane 1 disappeared; then the mixture was filtered, and the filter cake was washed with ethyl ether.…”

“…, let us replace Sinc;• by Sine,• U Sident,•. Thus, in Figure 10, for Sinc2 = (6,18), and Sident6 = (6,8), Sr = (6), and we replace Sinc2 by (6,8,18). If Sr is empty, then Sic,• is kept unchanged.…”

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.
