WebDeoxygenation of phosphine oxides represents a hot topic, as, on the one hand, the phosphines so obtained are important ligands in transition metal complexes, on the other, the regeneration of phosphines from phosphine oxides formed in different reactions, like in the Wittig- and the Mitsunobu reactions, means a challenge. WebPhosphine Oxides are normally classified as primary, secondary and tertiary oxides generally represented by the formula RPH2(O), R2PH(O) and R3P=O. The phosphine oxides are generally produced as a by-product of the Wittig reaction. Tertiary phosphine oxides are more stable than the primary and secondary phosphine oxides, and therefore least …
WebMar 2, 2016 · The 1-butoxy-3-phospholene oxide 2e was prepared in 83% yield ( Table 1, entry 17). The esterification of phosphinic acid 1 readily took place with n-pentanol and isopentanol at 180 °C after 30 min, giving complete conversions and yields around 94% ( Table 1, entries 18, 19). Webcommercially available phospholene oxide 3 as catalyst. Results and discussion The development of a catalytic Diaza-Wittig reaction can be divided in a four-step catalytic process.
