Anomeric pairs of L-arabinofuranosides of various aliphatic alcohols were synthesized and then investigated by n.m.r. spectroscopy. The "C-n.m.r. glycosylation shift of these L-arabinofuranosides is very similar to that of L-arabinopyranosides and other glycopyranosides reported previously. The 3JH.

Abstract
^1^H n.m.r. is used to show that α‐mercaptoacetone is formed as a mixture of monomer and a dimer. No evidence is found to support the previously claimed isolation of two dimeric species. The dimer dissociates to the monomer on standing as a solution in chloroform, but the monomer is dimerized by grinding. 1‐Mercapto‐3‐phenylpropan‐2‐one behaves similarly.

## Abstract Based on the Menschutkin reaction, α,ω‐alkanediamines with α,ω‐dibromoalkanes were employed to synthesize cationic polyelectrolytes named ionenes. By means of __in__‐__situ__ ^13^C NMR we have characterized the influence of ionic charges on the reactivity of the polymerizing species. Th
