Abstract:
The chemistry of allenes is an appealing topic which fascinates chemists nowadays. Their reactivity and versatility makes this skeleton a useful moiety to create a great variety of structures depending on the functional groups attached and the reaction conditions used. Recently, there is a growing interest in the study of the reactivity of bis(allenes) inspired in the chemistry developed in simple allenes. In this review a collection of examples of cyclization reactions of bis(allenes) is presented as well as the future perspectives.
