Popis: | Phosphoranes (I) and (II) also readily undergo addition at the triple bond in phenylacetylene to give functionally substituted quasiphosphonium ylids (III) and (IV), which have been previously obtained only with difficulty. Ylids (III) and (IV) are crystalline compounds with 31p NMR signals at 9 (III) and 18 ppm (IV). The structure of these compounds were also supported by IH, IH-{31P}, and 13C NMR spectroscopy. The composition was supported by elemental analysis. |
