In the presence of Rh2(OAc)4 as catalyst the cyclic α-diazo-β-dicarbonyl compounds 7a-c react with tert-butylphosphaacetylene 2 under elimination of nitrogen to furnish the 1,3-oxaphosphole derivatives 8a-c. The feasible competing reaction with formation of the 1,2,4-diazaphospholes 9a-c has not been observed.
