The syntheses of both the title compound and the endo-3-phenyl isomer are described.The isomer assignments were made on the basis of n.m.r. studies and confirmed by a crystal-structure analysis of the exo-3-phenyl compound.The crystals of C13H15OP are triclinic, space group P1, Z=2, with unit cell dimensions a=5.973(2), b=10.496(2), c=10.699(2) Angstroem , α=120.27(2), β=104.12(2), and γ=77.60(2) deg.The structure was solved by the heavy-atom method from diffractometer data and refined to an R value of 0.030.The phosphorinan ringadopts a chair conformation which is substantially flattened at the phosphorus end.The ring conformation, bond lengths, and valence and torsional angles are compared with those in several bicyclic and monocyclic systems reported in the literature.
