The 2H-phosphirene 4 is synthesized from the spirocyclic 3H-1,2,4-diazaphosphole 1 by low temperature photolysis.The isomeric 1H-phosphirenes 7 are formed by a -cycloaddition process of chloro carbenes, generated from diazirines, onto the triple bond of phosphaalkynes.When the 1-chloro-1H-phosphirenes 7 are allowed to react with a series of nucleophiles substitution occurs yielding the 1H-phosphirenes 9, 11 and 12.The existance of a phosphirenium cation, for instance 13 is discussed.
