- A novel, one-pot synthesis of α-C-cyanohydrazines in the presence of lithium perchlorate/diethylether solution (5.0 M)
-
Condensation of N,N-dimethylhydrazine, an aldehyde in lithium perchlorate/diethylether solution (5.0 M) gave N,N-dimethylhydrazone, which were treated with trimethylsilylcyanide to afford α-C-cyanohydrazine. These compounds are important precursors of nitrogen-substituted reagents.
