| Abstract: | Abstract In contrast to allenylphoephonio diohlorldes and dial-kyl eaters, the diamidea are little known and praotioally not studied. The allanylphoephonio diamides 2a-h were prepared from the 3,3-disubstituted allenylphoephonio diohlorldes 1a,b, CI2P(0)-CH=C=CR1R2, ad heterooyolic minee at law temperature.Here we report the results of the reaction of 2a-h with bromine. Unlike the halogenation of the oorresponding dialkyl esters, dichlorides and tertiary phosphine oxides, where only one reaction route has been observed-cycloadditlon or 2,3-additIon, both reaction routes proceeds in allied degree in the case studied: |
