Reactions of low-valent metal complexes with fluorocarbons. Part IX. Iridium and platinum complexes of bis(trifluoromethyl) thioketen and 1,1-bis(trifluoromethyl)ethene-2,2-dithiolate

Abstract

A mixture of the six- and five-membered heterocyclic compounds 3,6-bis-[2,2,2-trifluoro-1-(trifluoromethyl)-ethylidene]-s-tetrathian and 3,5-bis-[2,2,2-trifluoro-1-(trifluoromethyl)ethylidene]-1,2,4-trithiolan reacts with (Ph₃P)₄Pt, (Ph₂PMe)₄Pt, trans-(Ph₃P)₂Ir(CO)Cl, and trans-(Ph₂PMe)₂Ir(CO)Cl to form bis(trifluoromethyl)thioketen complexes (Ph₃P)₂Pt[(CF₃)₂CCS], (Ph₃P)₂Ir(CO)Cl[(CF₃)₂CCS], and (Ph₂MeP)₂Ir(CO)Cl[(CF₃)₂CCS], and the 1,1-bis(trifluoromethyl)ethene-2,2-dithiolate complexes (Ph₃P)₂Pt[(CF₃)₂CCS₂], (Ph₂PMe)₂Pt[(CF₃)_2^–CCS₂], (Ph₃P)₂Ir(CO)Cl[(CF₃)₂CCS₂], and (Ph₂PMe)₂Ir(CO)Cl[(CF₃)₂CCS₂].
