Abstract:N ,N'-(Alkanediyl)bisalkanamides with the following general formula have been synthesized and the El spectra have been examined: CH3(CH2)n-2NHCO(CH2)mHNCO(CH2)n-2CH3 in which m = 2,4, or 6; n = 6,7, 10,12 or 18. The results show that members of different series with different n and m have similar mode of fragmentation, there exist ions of cyclic structure which result from the fragmentation of the alkanediyl portion of the molecule. Ions of cyclic structure are quite common in the spectra of this class of compounds. In the 1 , 4-butanediyl series (i. e. m = 4) fragment ion with 4 membered ring has the highest relative intensity among all the cyclic ions, while in the 1, 6-hexanediy series (m = 6) the ion with 6 membered ring is the strongest. Fragment ion with m /z 70 is common to all spectra but it forms the base peak in 1 , 4-butanediylbisalkanamides.
