Hypercoordinated organosilicon compounds are intensively studied by many research groups due to their interesting structure and synthetic usability [1, 2, 3, 4, 5, 6, 7, 8, 9]. Pentacoordinated silicon derivatives N,N-disubstituted 5-(ammoniomethyl)-2,7-dioxo-1,4,6,9-tetraoxa-5-silaspiro[4,4]nonan-5-uides are known as electrostatically stable silanates [10]. Compounds of this type can be classified as zwitterions containing negatively charged pentacoordinated silicon atom and positively charged tetracoordinated nitrogen atom. Compound 1a, earlier synthesized by Erchak and co-workers [11], was the parent compound of this class of pentacoordinated silanates. Biological studies have revealed that compound 1a can be used as an agent accelerating the growth and development of plants and increasing the productivity of crops [12].

This article describes a novel method for the preparation of compound 1a using morpholin-4-yl-methylsilane ( 2) as the starting material. The previously reported...
