from the appropriate di-N-substituted imidoyl chloride with use of sodium hydrogen selenide to introduce selenium. The reduction of selenoesters to ethers has been demonstrated, as well as the ready reaction of these compounds with the methylene Wittig reagent.

Ammonium aromatic diselenoates were synthesized by reacting aromatic diselenoic acid 2-(trimethylsilyl)ethyl esters derived from aluminum 2-(trimethylsilyl)ethyl selenolate with aromaticselenoicacidO-methylesters with ammonium fluorides. The results of molecular structure analysis and NMR studies of ammonium salts supported the double-bond character between the carbon atom and selenium atoms.
