摘要

Oxidation of 3,4-dimethyl-1-phenylphosphole with peracids or peroxides gives arelatively stable P-oxide, which can be used in Diels-Alder reactions to give derivatives with the 7-phosphanorbornene framework. Oxygen insertion into a C-P bond of this framework occurs smoothly with m-chloroperbenzoic acid (MCPBA) providing derivatives of the 2,3-oxaphosphabicyclo octene ring system. The phosphole can be converted to this system in a one-pot synthesis by reaction with excess MCPBA in the presence of N-phenylmaleimide as dienophile. The phosphole oxide undergoes mono-epoxidation with MCPBA. Thermal or photochemical fragmentation of the 2,3-oxaphosphabicyclo ocetene is a useful source of the 3-coordinate species Ph-PO2, a meta-anhydride of phenylphosphonic acid. This species was trapped successfully with a variety of alcohols.
