Double bonds linked by C and P atoms

The RCM of diallylphenyl phosphane, eqn. (13), proceeds smoothly at 80°C in chlorobenzene (95% conversion in 5 h) when catalyzed by complex 1 of Ch. 3. The reaction occurs more readily than the self-metathesis of allyldiphenyl phosphane (10% conversion in 5 h). Steric hindrance evidently prevents the phosphorus atom from competing seriously with the olefinic bond for the vacant coordination position at the metal site (Leconte 1995a,b).
