The present invention relates to a process for the preparation of cyclic cis-diamines of formula
wherein Q is selected from the group consisting of -CH2-, -CH(CH3)-, -C(CH3)2-, -(CH2)2-,-(CH2)3- and -(CH2)4-;
n is an integer from 0 to 4;
and each substituent R, if present, is independently a linear or branched C1-8 alkyl attached to any one of the depicted carbon atoms;
starting from cyclic dienes such as cyclopentadiene and an azodicarboxylic acid derivative such as azodicarboxamide. Also claimed are novel compounds as intermediates in the process.
