24. Cell dimensions were determined by least squares refinement of the measured setting angles of 25 reflections with 4° < 20 < 50°. The structure was solved using MULTAN 80 analysis and refined by full-matrix least-squares techniques. Two different molecules are found in the unit cell. These differ by a variation of torsion angles in the triphenylphosphine P - C bond.

29. 2, the solution was vigorously stirred and 3 mmol of 1-hexene was syringed into the solution. The hydrogenation rate was followed by measuring the rate of hydrogen uptake. A similar experiment was carried out in the presence of mercury as a radical scavenger with no appreciable change in the rate of hydrogen uptake. After completion, the reaction products were identified by GCMS, which showed total conversion to hexane.
