摘要

A new rearrangement is observed during the treatment of quaterny salts of diacetylene- Mannichbases with aqueous alkalies; under these conditions 1-diethylamino-2, 4- heptadiyne-methojodid smoothly yields 1-hepten-3, 5-diyne. The decomposition of 1- dialkylamino-2, 4-alkadiynemethojodids with more than 7 C-atoms gives mixtures of 1-alken- 3, 5-diynes, cis and trans-5-alken-1, 3-diynes an cis-and trans-6-alken-2, 4-diynes. It is ...
