Other complexes with cyclic thioethers are those with 3,3,6,6-tetramethyl-l-thia-cyclohep-tine,3057 7-toluensulfonyl-7-aza-l,4-dithiacyclononane (570),3058 or l,10-dithia-4,7,13,16-tetraoxa-cyclooctadecane.3059 With the cyclic selenoethers [8]aneSe2 and 3H-l,4,5,7-tetrahydro-2,6-benzodiselenonine the dinuclear complexes [Au2Cl2L] have been obtained, these are thought to involve linear Se—Au—Cl fragments. 152...

The structural parameters describing the geometry of di-/inter-halogens binding to chalcogen-containing molecules (thioethers, selenoethers, thiocar-bonyl, and selenocarbonyl compounds) are defined in Figure 1. 

With selenium only a handfull of reactions has been published, involving both propargyl selenoethers [187, 188] and alkynyl selenoethers [312],... 

Trifluoromethyl thioethers are produced in a fluoride-catalysed one-pot reaction of alkyl or aryl thiocyanates with trifluoromethyl silanes [37]. The reaction is initiated by fluoride ion displacement of the trifluoromethyl anion from the silane the thioether is formed from the thiocyanate by displacement by the trifluoromethyl anion of the cyanide ion, which then perpetuates the reaction. Trifluoromethyl selenoethers are obtained by an analogous route. In a similar manner, disulphides can be converted into trifluoromethyl thio- or selenoethers [38],...

A number of organoselenium reagents have been used as efficient initiators of ring closure, leading from unsaturated substrates to the lactones and cyclic ethers (81T4097). The reaction is termed phenylselenoetherification. The phenyl selenoethers obtained are subject to a selection of transformations, e.g. their conversion to allylic ethers (Scheme 50) and their...

Alternatively, the complexes can be prepared by direct addition of the thioether or selenoether to AuCl (equation 27).219...
