(Selenocarbamoyl)silanes and -germanes: Their Synthesis Using (Selenocarbamoyl)lithium and Characterization

Deprotonation of the selenoformyl group in N,N-dibenzyl selenoformamide with LDA, followed by silylation and germylation of the resulting anion with Me3SiCl and Me3GeCl, gives (selenocarbamoyl)silane and -germane in moderate to good yields. The molecular structures of these products and the starting selenoformamide were characterized by using X-ray analyses.
