Use of Polyanions for Alkylation of Hydrazine Derivatives
摘要:
Alkylation of hydrazine and its derivatives still remains a quite complicated task. The novel method utilizing the polyanion strategy is reported. Formation and use of trianion for alkylation of hydrazine derivatives is first reported. Described method provides fast and convenient access to multialkylated derivatives. Scope and limitations of new method are also investigated.

The synthesis and the crystal structure of N2-dibenzyl-N1-butoxycarbonyl hydrazine are reported. The compound was prepared from commercially available t-butyl carbazate. It crystallizes in the triclinic space group P 1 with a = 5.479(1) angstrom, b = 9.559(1) angstrom, c = 9.748(1) angstrom, alpha = 63.81(1)-degrees, beta = 87.52(1)-degrees, gamma = 74.07(1) angstrom, Z = 1, D = 1.18 g/cm3. The structure was solved by direct methods and refined to R = 0.0329.
