Abstract

The first synthesis of push-pull-diacetylenes of type 4 is described. Reaction of perchloro-butenine (13) with 2 equivalents of dialkylamine, followed by filtration and dechlorination by means of 2 equivalents of butyllithium gives lithium-dialkyl-amino-diynes (15). Final acylation of these intermediates leads to push-pull-diacetylenes 4b, 4c and 4d in good yields. The method allows the introduction of both push- and pull-substituents in a simple one-pot-procedure.
