Nature of the heavy formal double bonds As[double bond, length as m-dash]Ch, Sb[double bond, length as m-dash]Ch and Bi[double bond, length as m-dash]Ch (Ch = S, Se, Te) in NCN-pincer supported arsinidene, stibinidene and bismuthinidene chalcogenides.

ABSTRACT: The synthesis of arylpnictinidenes 2,6-(Ph₂PNMes)₂C₆H₃Pn based upon a novel bis(phosphine imine) NCN-pincer ligand is reported (Pn = As, Sb, Bi). The oxidation of 2,6-(Ph₂PNMes)₂C₆H₃Pn with sulfur, selenium and tellurium, respectively, afforded arylarsinidene chalcogenides 2,6-(Ph₂PNMes)₂C₆H₃AsCh, arylstibinidene chalcogenides 2,6-(Ph₂PNMes)₂C₆H₃SbCh and arylbismuthinidene chalcogenides 2,6-(Ph₂PNMes)₂C₆H₃BiCh, which can be formulated as containing terminal As[double bond, length as m-dash]Ch, Sb[double bond, length as m-dash]Ch and Bi[double bond, length as m-dash]Ch doubl
