Correction- The ¹³C NMR Spectrum of N-Ethyl-N-methylformamide

Cyclic Imino Ethers, Polymerization

“…As revealed by 13 C-nmr spectroscopy, isotactic poly(N-formylpropyleneimine) (16) is composed of four possible dyad structures arising from restricted rotation around the N-CHO bond (30).…”

“…2-Mercaptoalkyl-2-oxazolines (30) have been prepared (42); an intermediate (31) was obtained from Lawesson's reagent and a 2-oxazoline containing a hydroxy group (43,44); and (30) and (31) give poly(amide-thioether) derivatives. …”
