Synthesis and X-ray crystal structure of 1,2,3-triphenylphosphirene
Abstract
1,2,3-Triphenylphosphirene is prepared from its P→W(CO)5 complex by a two step decomplexation procedure involving iodine and 1-methylimidazole; its X-ray crystal structure analysis shows a very strained ring (< CPC = 41.8°) with no electronic delocalization.
