Selenide - Wikipedia
Most elements form selenides. They sometimes have salt-like properties, e.g. sodium selenide, but most exhibit covalent bonding, e.g. molybdenum diselenide. Their properties are diverse, mirroring the diverse properties of the corresponding sulfides.
Selenide - an overview | ScienceDirect Topics
Selenides are efficient leaving groups in elimination chemistry. β-Hydroxy selenides can be obtained from epoxides by trans opening of epoxides with a suitable selenol and subsequent elimination to provide various di-, tri- or tetrasubstituted alkenes in a …
Selenide - Simple English Wikipedia, the free encyclopedia
Selenide is an ion. Its chemical formula is Se 2–. Selenides are similar to sulfides. Selenides are reducing agents when pure. They are stronger reducing agents than sulfides. Selenide ores are the source of selenium. Selenides are normally mixed with sulfides. The selenide ion is unstable except in very basic conditions.
