Preparation and reactions

Sodium diethyldiselenocarbamate is obtained by treating carbon diselenide with diethylamine in the presence of sodium hydroxide:[2]

CSe2 + HN(C2H5)2 + NaOH → NaSe2CN(C2H5)2 + H2O

Other diselenocarbamates can be prepared similarly from secondary amines and carbon diselenide. The related diselenoxanthates have also been prepared.[2]

Diethyldiselenocarbamate forms coordination complexes with many transition metals.[1] With Se(II), it forms the bicyclic Se(Se2CN(C2H5)2)2.[3]

Structure and bonding

The C2NCSe2 core of the diethyldiselenocarbamate anion and its complexes is planar, indicating some C–N multiple bond character.[4]
