Mathey, Francois published the artcilePyrolysis of some phosphorus trihalide-diene addition compounds, Recommanded Product: 2,3-Dibromo-2,3-dimethylbutane, the publication is Comptes Rendus des Seances de l’Academie des Sciences, Serie C: Sciences Chimiques (1969), 268(21), 1902-4, database is CAplus.
Pyrolysis of H2C:-CMeCMe:CH2.PBr3, H2C:CMeCMe:CH2.PCl3, and H2C:-CMeCH:CH2.PBr3 in vacuo at <200° gave, resp., PBr3 or PCl3 and Me2CBrCBrMe2, ClCH2CHMeCClMe2 or BrCH2CH2CBrMe2 together with polymeric residues. The products were identified by their N.M.R. spectra, which are discussed.
