| Abstract: | Unstable β-phosphaenones formed by reaction of the phosphanylidene-σ4-phosphorane DmpP = PMe3 (Dmp = 2,6-dimesitylphenyl) with acenaphthenequinone dimerize in hexane by a formal 4+4] cycloaddition reaction to form a cyclic diphosphinite. X-ray crystallographic analysis and variable temperature 1H NMR spectra of the cyclic diphosphinite are presented. |
