Main-group-bridged [1]ferrocenophanes enable the incorporation of a variety of elements into polyferrocene materials through ring-opening polymerization. While antimony-containing materials have been used as flame retardants and photolithographic resists, there exists only a single example of a Sb(III) main-chain polymer. We have used the ring-opening of a stiba[1]ferrocenophane as a facile route to expand the family of Sb(III) main-chain polymers. Two examples of stiba[1]ferrocenophanes were synthesized and characterized, featuring bulky mesityl and terphenyl substituents at antimony, fc(SbMes) and fc(SbTer). fc(SbTer) was found to undergo thermal ring-opening polymerization to form a soluble and robust polymeric material, PFSbTer. These results further expand the range of polyferrocenes and provide access to a new class of Sb(III)-containing materials.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
