| Abstract: | Dodeca-1,3-diynyl ketones were synthesized by isomerization of dodeca-5,7-diyne with H2N(CH2)2NHLi and treatment of the in situ prepared lithium derivative of dodeca-1,3-diyne with N-methoxy-N-methylcarboxamides.
Dedicated to Corresponding Member of the Russian Academy of Sciences E. P. Serebryakov on the occasion of his 70th birthday.
