Abstract A series of 2‐(1, 3‐dioxolan‐2‐yl) phenylallenes that contained a range of
substituents (alkyl, aryl, phosphinyl, alkoxycarbonyl, sulfonyl) at the cumulenic C3 position …

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 …

The construction of a new type of bicyclo [4.4. 0] decene products with a conjugated
exocyclic diene unit was developed using Rh-catalyzed cyclization of 1, 5-bisallenes in the …
