- Abstract
Glaser homocoupling of N,N-bispropargyltriflamide led to the formation of N,N'-hexa-2,4-diyne-1,6-diylbis( N-prop-2-yne-1-triflamide). Further condensation into a 14-membered heterocycle, 1,8-bis-(triflyl)-1,8-diazacyclotetradeca-3,5,10,12-tetrayne did not occur evidently because of rigid steric requirements to the cyclization. In the Glaser heterocoupling of N-propargyltriflamide with arylacetylenes ArC≡CH (Ar = Ph, p-CNCH) the condensation products formed in 20-30% yields.
