## Abstract Reaction of an iminophosphorane **2** bearing the Martin ligand with dimethyl acetylenedicarboxylate, followed by a ring opening reaction of a [2+2]‐cycloadduct between them, gave the corresponding α‐iminoalkylidenephosphorane **3**, which was hydrolyzed to afford 1,2λ^5^‐oxaphosphol‐5(
## Abstract Some 1,2,4‐triazolo[1,5‐__a__]pyrimidin‐5‐one derivatives 1 and their alicyclic condensed ring analogues 2‐3 were converted through the corresponding “imino chlorides” 4‐6 to the oximes 7‐9. The “__E__” isomeric structure of the products obtained was proven with the use of cmr using the
