Abstract

Abstract : While 1, 2σ 5 λ 5 -oxaphosphetanes are well known intermediates from the Wittig-reaction, no 1, 2σ 3 λ 3 -oxaphosphetanes have been described, so far. First investigations towards metal coordination and P-oxidation, as well as DFT calculations on retro-[2+2] cycloaddition reactions of the 1, 2-oxaphosphetane ring are presented. Abstract : While 1, 2σ 5 λ 5 -oxaphosphetanes are well known intermediates from the Wittig-reaction, no 1, 2σ 3 λ 3 -oxaphosphetanes have been described, so far. Herein, we present the first synthesis of 1, 2σ 3 λ 3 -oxaphosphetanes derived from their κP–Mo(CO)5 complexes and first investigations towards metal coordination and P-oxidation. Bonding, ring strain energy and potential retro-[2+2] cycloaddition reactions of the 1, 2-oxaphosphetane ring were studied by DFT methods.
