## Abstract The addition of dichlorocarbene to the double bond of 1‐alkoxy‐dihydrophosphole oxides and subsequent thermolysis of the adduct so obtained affords mixtures of the two double bond isomers of alkoxy‐dihydrophosphinine oxides, if the latter step is carried out in the presence of triethyla
The double bond of the P-alkoxy 3,4-dimethyl-2,5dihydro-1 H-phosphole I -oxides reacts easily with dichlorocarbene to give two diastereomers of an unstable adduct useful in the synthesis of ring expanded products, such as I ,2-dihydrophosphinine oxides or I ,2,3,6-tetrahydrophosphinine oxides. The f
