| The study of carbon-rich materials encompasses a variety of themes, notably alkyne-based and extended aromatic systems. But while the study and synthesis of the highly-conjugated dehydroannulene, dehydrobenzoannulene and organometallic dehydroannulene systems has progressed for some years now, as of yet no efforts have been made towards the synthesis of heterocyclic organometallic dehydroannulenes and their derivatives. Over the last few months we have taken knowledge obtained from our earlier syntheses of organometallic dehydroannulenes to generate analogs in which the perimeter benzenes are replaced by heteroaromatic rings. In doing so, a class of compounds exhibiting "explosive" thermal decomposition has been realized. Furthermore, the inclusion of heteroatoms imparts the potential for intermolecular electronic communication in these systems. Derivatives lacking the butadiynyl bridge between perimeter rings are shown to coordinate transition metals to the heteroatoms, generating novel bimetallic systems with potentially interesting electronic and catalytic properties. |
