Abstract

1,2,3-Triphenylphosphirene is prepared from its P-+W(CO)5 complex by a two step decomplexation procedure involving iodine and I-methylimidazole; its X-ray crystal structure analysis shows a very strained ring (< CPC = 41 -8") with no electronic delocalization. ... The heterocyclic analogues of cyclopropene --e=v--X have been shown to be highly unstable whenever the heteroatom bears a lone pair which can interact efficiently with the carbon-carbon double bond. Such is the ...
