Abstract
In this paper a new cycloisomerization pattern of 1,5-bisallenes based on the catalyst and substituent effects has been reported. A range of seven-membered cross-conjugated trienes 7 would be obtained efficiently via the beta-H elimination and reductive elimination of the intermediates formed via cycloisomerization.
