Giumanini, Angelo G. published the artcileRevisitation of the formaldehyde-aniline condensation. VIII. Monomeric N-methyleneanilines, COA of Formula: C14H23N, the publication is Journal fuer Praktische Chemie (Leipzig) (1988), 330(2), 161-74, database is CAplus.
A convenient, high yield method for the preparation of monomeric N-methyleneanilines I (R = Me, Et, CHMe2; R1 = H, 4-Br, 3-O2N) and the characterization of the products by mass spectrometry, 1H- and 13C-NMR, and IR are reported, improving previous procedures and describing new compounds The existence of monomeric N-methyleneanilines is strictly related to the presence of enough steric hindrance to prevent oligomerization by substituents in ortho positions. Some imines are tentatively identified on the basis of the observed mass spectrum of the reaction mixture I (R = Me, R1 = H) provided an example of a mobile equilibrium between a monomeric and trimeric imine.
