Abstrakt:	The first stable enols in 1,2-dihydrophosphetes 6and 10were synthesized and structurally characterized with intermolecular hydrogen bonds to phosphoryl groups in 10-membered dimeric structures; in contrast, trivalent analogue 9exists in keto-form, where such stabilization by hydrogen bonds is not feasible.
