Steric hindrance was observed during the oxidation of 2,4,6-tri-tert-butylphenylphosphole to the P oxide and in the dimerization of this latter species to the corresponding phosphanorbornene derivative. Single-crystal X-ray analysis of the dimer revealed considerable steric crowding around the P ato
## Abstract A simple two‐step synthesis of a series of ether‐type bridged biaryls 3, as favorable models for studies of helimerization processes, is described. Starting from the known corresponding lactones 1, a variety of differently substituted representatives 3 is prepared, greatly varying by th
