✦ Synopsis

Synthesis and Photolysis of Phosphiranes and Diphosphiranes Carrying Sterically Protecting Groups on the Phosphorus Atoms.

-Photolysis of phosphiranes and diphosphiranes possessing a tri-tert-butylphenyl group at the P-atoms proceeds selectively to furnish phosphaindane (XI) as the major product (no yields are given). On the other hand, the inertness of the novel 2,6-dimesityl-4-methyl-phenylphosphirane (VII) under analogous photolysis conditions demonstrates that introduction of the 2,6-dimesityl-4methylphenyl group in place of the tri-tert-butylphenyl group dramatically decreases the photoreactivity.
