• 2,4-Diethoxy-1,3-diphenyl-1,3,2,4-diazadiphosphetidine (<B>1a</B>) reacted with benzil, benzalacetophenone, and α-phenyliminobenzyl phenyl ketone in refluxing <I>o</I>-dichlorobenzene to give 2-ethoxy-3,4,5-triphenyl-<I>Δ</I><SUP>4</SUP>-1,3,2-oxazaphospholine 2-oxide, 2-ethoxy-1,3,5-triphenyl-<I>Δ</I><SUP>4</SUP>-1,2-azaphospholine 2-oxide, and 2-anilino-3,4,5-triphenyl-<I>Δ</I><SUP>4</SUP>-1,3,2-oxazaphospholine 2-oxide, respectively. Under mild conditions, reaction of <B>1a</B> with benzil gave a Ramirez type 1:2 adduct, which thermally decomposed to give oxazaphospholine derivatives.
