Main-Chain Boron-Containing Oligophenylenes via Ring-Opening Polymerization of 9-H-9-Borafluorene

9-H-9-Borafluorene (H8C12BH; 5) can be generated in situ from 9-Br-9-borafluorene and Et3SiH in benzene or hexane. Monitoring of the reaction by NMR spectroscopy at rt in C6D6 reveals that 5 forms C 1-symmetric dimers (5)2 under these conditions. DFT calculations on conceivable isomers of (5)2 and a...
