The chemistry of chalcogenones – compounds containing a heavier chalcogen–carbon double bond, CE (E = S, Se or Te), i.e. a thione, selone, or tellone functional group – has been developed extensively over a number of years, e.g., chalcogenoketones,1 chalcogenoamides,2a,b chalcogenoureas, and related N-substituted derivatives,2a,b,3 as well as a number of other related classes of compounds,4 including the so-called “heavy ketones” – species with a double bond between tetrels (Si, Ge, or Sn) and chalcogens (S, Se, and Te).5 The chemistry of compounds with a heavier chalcogen–phosphorus double bond, PE (E = S, Se, or Te) was also developed considerably during recent years as revealed by several book chapters dedicated to this topic.6 Moreover, for most of these classes of compounds the coordination chemistry toward transition or main group metals was quite thoroughly investigated. In many cases excellent reviews are available, e.g., p- and d-block metal complexes with thio-, seleno-, or telluroureas and related heavy chalcogen–carbon multiple-bond compounds,3b,c,7 metal complexes with species containing PE (E = S, Se, or Te) bonds,6a,d also emphasizing their potential as catalysts, precursors in materials chemistry, or compounds with biological activity.
