- Synthesis and structure of copper(II) phosphonodithioite complexes
-
A series of new complexes of CuBr with phosphonodithioites were prepared and characterized by NMR and IR spectroscopy. As shown by single crystal X-ray diffraction, diethyl tert-butylphosphonodithioite forms with CuBr a tetrameric cubane-like complex with the monodentate coordination of the organophosphorus ligand via the P atom.

- Evidence for Iron-Catalyzed α-Phosphinidene Elimination with Phenylphosphine
-
The ubiquitous half-sandwich iron complex [CpFe(CO)2Me] (Cp=η5-C5H5) appears to be a catalyst for α-phosphinidene elimination from primary phosphines. Dehydrocoupling reactions provided initial insight into this unusual reaction mechanism, and trapping reactions with organic substrates gave products consistent with an α elimination mechanism, including a rare example of a three-component reaction. The substrate scope of this reaction is consistent with generation of a triplet phosphinidene. In all, this study presents catalytic phosphinidene transfer to unsaturated organic substrates.

- INTERACTION OF DISULFIDES AND SULFENYLCHLORIDES WITH C-N,N-DIALKYLAMINOSUBSTITUTED PHOSPHAALKENES
-
Interaction of dialkyl disulfides with C-N,N-dimethylaminomethylene-P-phenylphosphine 1a results in the complete cleavage of the P=C double bond and formation of S,S-dialkylphenyldithiophosphonites.Ethyl sulfenylchloride undergoes dehydrochlorination by 1a, while phenyl sulfenylchloride cleaves the P=C bond in C-N,N-dialkylaminosubstituted phosphaalkenes with the predominant formation of either PhP(SPh)2 6 or PhP(SPh)Cl 7 depending on the phosphaalkene used and reaction conditions. Key words: C-(N,N-dialkylamino) substituted phosphaalkenes; disulfides; sulfenylchlorides.
