Reaction Steps

The procedure described in Example 1 (a) is essentially repeated except that 2.8 g of triphenylphosphine, 110 g (1.13 mols) of N-isopropylidene-propenylamine [prepared by reacting acetone with allylamine; cf. B. A. Kazanskii et al., Zhurnal Organicheskoi Khimii, Volume 6, No. 11, 2197-9 (1970)] and 108 g (2 mols) of 1,3-butadiene are used. Distillation yields 187.0 g (0.91 mol) of 3,12,12-trimethyl-1-aza-1,5,9-cyclododecatriene; boiling point 66° C./0.03 mm Hg; nD20 =1.4895.
