The perfluorovinyl complex trans-( Ph,P),Pd(CF: CF,) Br is formed by treating tetrakis(tripheny1phosphine)palladium with bromotrifluoroethylene. Analogous vinyl complexes trans-(Ph,PMe),Pd(CF: CF,)X (X = CI or Br) are obtained from (Ph,PMe),Pd and CF2:CFX (X = CI or Br). n-Heptafluoroiodopropane reacts with (Ph,PMe),Pd to form trans-(Ph,PMe),Pd(C,F,)I.n-Heptafluorobutyryl chloride reacts to form the acyl complex trans-(Ph,PMe),Pd(COC,F,)CI, whereas, pentafluorobenzoyl chloride affords trans-(Ph,PMe),Pd(C,F,) CI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
