Abstract: Provided are novel dihydro-1H-phosphole 1-oxide derivatives and a preparation method thereof. More particularly, the dihydro-1H-phosphole 1-oxide derivatives include 1,3-dihydro-1H-2,1-oxaphosphole 1-oxide derivatives and 2,3-dihydro-1H-2,1-azaphosphole 1-oxide derivatives. Further, in the preparation method of a dihydro-1H-phosphole 1-oxide derivative according to the present invention, various phosphinine oxide derivatives may be prepared with high yield by a simple synthesis process by reacting a phosphinic derivative and a vinyl derivative with each other in the presence of a rhodium (Rh) catalyst, an oxidant, and a base.
