Chemistry and Pharmacology
Sulfur and selenium react with a 1,2-dihydrophosphete P-W(CO)5 complex at ca. 120°C to give the corresponding 2,5-dihydro-1,2-thiaphosphole and 2,5-dihydro-1,2-selenaphosphole complexes, respectively. These products result from an insertion of S or Se into the P—C sp3 bond of the four-membered ring.
