Certain reactions of 2,2,2-trialkoxy-Δ4-oxaphospholenes

Abstract

1. β-(Dimethylphosphono)propionaldehyde was obtained by hydrolysis of 2,2,2-trimethoxy-Δ4-oxaphospholene. 2. Upon reaction of 2,2,2-trimethoxy-Δ4-oxaphospholene with acetic acid and acetic anhydride, opening of the phosphorane ring occurs of the P-O bond with for mation of β-(dimethylphosphono)propionaldehyde and its enol acetate, respectively. © 1969 Consultants Bureau.
