Syntheses and structure of bis(pentamethylcyclopentadienyl)dithiophosphinato complexes
1997
Bis(pentamethylcyclopentadienyl)phosphane Cp*2PH reacts with sulfur under basic conditions to give the corresponding dithiophosphinate salts M+ CP*2PS−2 (5 M+ = HNEt+3, 6 M+ = Li+), which are formed via the intermediate CP*2P(S)H (4). Both salts on treatment with cobalt(II) chloride give rise to the transition metal dithiophosphinate 7. The structures of this new type of diorganodithiophosphinate complexes in the solid state have been investigated. © 1997 John Wiley & Sons, Inc. Heteroatom Chem 8: 521–525, 1997
Bis(pentamethylcyclopentadienyl)-Substituted Phosphanes: Synthesis and Structure
1998
The bis(1,2,3,4,5-pentamethyl-1,3-cyclopentadien-1-yl)phosphanes 3−7 are formed in good yields by the reaction of the halogenophosphanes 2a or 2b with the appropriate nucleophile. Following another route, the dialkylaminobis(pentamethylcyclopentadienyl)phosphanes 11a−c have been synthesized by the treatment of dichloro(dialkylamino)phosphanes with two equivalents of (pentamethylcyclopentadienyl)lithium. The compounds 3−11 have been characterized by multinuclear NMR spectroscopy and 3, 5, 6, and 11a have also been characterized by single-crystal X-ray diffraction studies. The molecular structure of 11a is governed by steric congestion, which typically would lead to a parallel arrangement of …
