Conclusions 1. A general method was proposed for the structural determination of trialkylsilylated derivatives of N-acyl- and N-carboalkoxyhydrazines using15N NMR spectroscopy. The15N NMR chemical shifts, $$J_{^{15} H,^{29} Si} $$ and $$J_{^{15} NSiC^1 H} H$$ parameters characteristic for these compounds were found. 2. 1,2-Bistrimethylsilyl-1,2-dicarbomethoxyhydrazine is a mixture of the three possible “amide” conformers, while the bistrimethylsilyl derivative of 1,2-diacetylhydrazine is a symmetrical “imide” isomer with trans orientation of the methyl groups relative to the unshared pairs of the nearest nitrogen atoms.
