摘要：

Insertion of zirconocene into the C-X bond of 2-halophosphinines (X = Cl, Br) takes place between -80 and 20-degrees-C in tetrahydrofuran (THF); the X-ray crystal structure analysis of such an insertion product shows a normal geometry at zirconium and a highly delocalised phosphinine ring with all C-C and the two P-C bonds being strictly equal at 1.395 and 1.726 angstrom, respectively; protonation, deuteriation and halogenation of these products lead to the expected phosphinines by cleavage of Zr-C bond.
