AI Article Synopsis
- The synthesis of a 1,2σλ-oxaphosphetane from ethylene oxide is discussed, followed by its reactions with alkyl halides to produce β-halo phosphane oxides via an Arbuzov-type reaction.
- When using methyl triflate as a strong electrophile, the process resulted in cationic oligomerization of 1,2-oxaphosphetanes.
- DFT calculations suggest that 1,2-oxaphosphetan-2-iums serve as intermediates and highlight the differences between the Arbuzov reaction mechanism and a possible Perkow reaction pathway.
Article Abstract
Herein, we describe the synthesis of a 1,2σλ-oxaphosphetane from ethylene oxide and its reactions with alkyl halides to form β-halo phosphane oxides in an Arbuzov-type reaction. When methyl triflate was used as a hard electrophile, cationic oligomerisation of 1,2-oxaphosphetanes was observed. DFT calculations indicate 1,2-oxaphosphetan-2-iums as intermediates and reveal differences between the Arbuzov and the potential Perkow reaction pathway.
