Reaction of C₇H₈PtCl₂ with CF₃SAg in dichloromethane solution results in the replacement of both chlorine atoms with CF₃S groups to give white crystalline C₇H₈Pt(SCF₃)₂. However, the analogous reaction of C₇H₈PdCl₂ with CF₃SAg results in addition of CF₃S groups to the norbornadiene ligand to give the two yellow crystalline products [(C₇H₈SCF₃)Pd]₂Cl₂ and [(C₇H₈SCF₃)Pd]₂(Cl)(SCF₃) shown by their proton nmr spectra to be novel nortricyclyl derivatives. Reaction of the tetraphenylcyclobutadiene complex [(C₆H₅)₄C₄PdBr₂] ₂ with CF₃SAg in dichloromethane solution gives golden red (C₆H₅)₄C₄Pd-(SCF₃) ₂ formulated as a monomeric 16-electron tetraphenylcyclobutadiene complex. However, reaction of (C₆H₅)₄C₄Co-(CO)₂Cl with CF₃SAg gives the dark red binuclear complex [(C₆H₅)₄C₄Co(CO)SCF ₃]₂. The structures of these new compounds are discussed.
