S 98 Synthesis and properties of water-soluble 2-aminomethylidene derivatives of 1,3-dicarbonyl compounds [Electronic resource] / D. N. Bazhin, Yu. S. Kudyakova, T. I. Gorbunova, Ya. V. Burgart, A.

It was shown that further alkylation of aminomethylidene derivatives with methyl iodide occurs regioselectively at the tertiary nitrogen atom. Quaternization products obtained exhibit high corrosion inhibition of mild steel in hydrochloric acid medium \\\\expert2\\nbo\\Russian Journal of General Chemistry\\2013, V. 83, N 7, p. 1330–1335.pdf |
