Abstract
In the presence of Rh-2(OAc)(4) as catalyst the cyclic alpha-diazo-beta-dic
arbonyl compounds 7a-c react with tert-butylphosphaacetylene 2 under elimin
ation of nitrogen to furnish the 1,3-oxaphosphole derivatives 8a-c. The fea
sible competing reaction with formation of the 1,2,4-diazaphospholes 9a-c h
as not been observed.
