Gaseous sulfurdioxide reacts with 1,1-dimethylhydrazine, N-aminopiperidine, N-aminohomopiperidine, and N-aminomorpholine to form 1:1 adducts. The adducts are formed between the nitrogen atom of the R2N group in the hydrazine and the sulfur atom in sulfurdioxide. Analytical, proton NMR and i.r. spectral data are given.

Pastes of alpha-cyanoacrylic acid esters and insolluble fillers can be applied to surfaces submerged in water for securing thereto, in situ, a wide variety of metallic and non. metallic substances.
