ARAUJO, Maria Helena et al. Novel Organophosphorus Cage Compound Produced by an Unexpected Oxidative Coupling of 1,2,4-Triphosphole: Crystal and Molecular Structures of Two Isomers of Formula P6C4But4 CHSiMe3. J. Braz. Chem. Soc. [online]. 2002, vol.13, n.5, pp. 555-558. ISSN 1678-4790. http://dx.doi.org/10.1590/S0103-50532002000500002.
Reaction of Li(P3C2But2 ) with BrCH(SiMe3)2 results in a novel organophosphorus compound with the formula, P6C4But4 CHSiMe3 (1). Compound 1 was fully characterised spectroscopically and its unique molecular structure determined by single crystal X-ray diffraction. Another isomer (2) with a saturated structure was also fully characterised.
