Highly efficient generation of ammonium eneselenolates, their reactions and electronic properties
The ammonium eneselenolates generated from selenothioic acid S-esters and ammonium fluoride were reacted with carbon electrophiles to furnish ketene selenothioacetals with high stereoselectivities. The spectroscopic properties of the ammonium eneselenolates have suggested that the electrons on the selenium atom efficiently delocalize on the carbon-carbon double bond.
