The ease with which selenium combines with many other elements to form binary compounds has already been mentioned (p. 299). Only one compound with hydrogen is known, but a series of polyselenides of the alkali metals corresponding to the polysulphides has been obtained. Selenium forms a hexafluoride, SeFG, but no other hexalialide has been isolated. The tetrahalides arc the most stable, and mixed chloro-bromides of quadrivalent selenium, SeCl Br, are known. Selenium monochloride, SeaCla, and selenium monobromide, Se2Br2, also exist as comparatively stable liquids at ordinary temperatures. No compound of selenium and iodine is known. Selenium oxychloride, SeOCl2, and the oxybromide, SeOBr2, are extremely reactive and useful compounds. 

Selenyl Chloride, Selenium Oxychloride, SeOCl2, may be prepared in the following ways ... 

Selenium oxychloride is not the only inorganic solvent used for liquid lasers, several studies use as solvent phosphorus oxychloride, POCl3 (Blumenthal et al., 1968 Brecher and French, 1969 Brinkschulte et al., 1972). Although this solvent is a worse host for ionic salts due to its lower dielectric constant, it is much more attractive for liquid laser uses since it is far less toxic and corrosive than SeOCl2. The approach for the preparation of POCl3 solutions is slightly... 

A small number of reports on the chemistry of selenophenes and tellurophenes appeared during the past year. A selenium transfer reaction between the bis-anion derived from phenylenediacetonitrile and selenium oxychloride (SeOCl2) gave the corresponding... 

An inorganic selenium electrophile, selenium oxychloride (SeOCl2), has been utilized to prepare fused selenophenes <2002JOC2453>. Deprotonation of bis(cyanide) 104 with LDA followed by treatment with selenium oxychloride gave the benzo[c]selenophene 105 (Equation 15). This sequence also allowed for the preparation of a thieno[3,4-f]selenophene. 

Selenium hexafluoride (SeFj) Selenium oxychloride (SeOCl2)... 

If the oxychloride is applied in dilute benzene solution some nitrogen selenide or selenium nitride is also formed.3 With liquid ammonia in the presence of ether in open vessels, the primary product is the compound SeOCl2.4NH3, which is decomposed by water into selenium, selenium nitride, ammonium chloride, ammonium selenite and selenious acid in a sealed tube, selenium nitride is formed in comparatively good yield.4... 

ROH -> RCl. Chlorotrimethylsilane itself does not convert alcohols into alkyl chlorides, but this conversion proceeds readily in the presence of Se02. The actual reagent is believed to be selenium(IV) oxychloride, SeOCl2, which can be isolated in 74% yield from the reaction of SeO, with ClSi(CH,),.
