Özet
Two general routes are described for the synthesis of the title compounds from the reaction of either (A) the dimethyl acetal of N,N-dimethylformamide and an appropriate N,N?-bis(secondary amine), or (B) sodium hydride and a 4,5-dihydroimidazolium or tetrahydropyrimidinium salt. The following new compounds have been made: (Chemical Equation Presented) X-Ray data on crystalline [CN(R)(CH2)2NR]2 (R = CH 2Ph) and (2b) [data in parentheses] show a short C=C bond, 1.319(8) Å [1.329(5) Å], long Csp2-N bonds, av. 1.437(11) Å [1.424(4) Å], with each of the four nitrogen atoms in a pyramidal sp 3 environment.
