The reactions of lithium derivatives of sydnones with 1,3-dichloro-1,1,3,3-tetramethyldisiloxane have been studied. The first representatives of sydnon-4-yl substituted disiloxanes and silicon macrocyclic derivatives of sydnones were obtained and their molecular structures were studied by X-Ray and ¹H, ¹³C, ²⁹Si, and ¹⁵N NMR spectroscopy.
