A stereoselective aminoiodination of activated alkynes withPhI(OAc){2|two} and amines {via|by way of|through|by means of} multiple-sitefunctionalization to afford (Z)diethyl2-(diphenylamino)-3-iodomaleate derivatives with superior yields has been described.The {key|important|crucial|essential} {feature|function} of this reaction…

Frequency-selective Heteronuclear Correlation (FS-HETCOR) Experiments in Solid-State NMR

Heteronuclear correlation (HETCOR) is {critical|crucial|vital|essential|important} to {obtain|acquire|get|receive} structural {information|info|details|data|facts|information and facts} in solid-state nuclear magnetic resonance (NMR). We propose novel frequency-selective Heteronuclear correlation (FS-HETCOR) experiments to selectively {enhance|improve|boost} the inter-atomic…
