Abstract

Three phosphines and their corresponding oxides bearing one 2-pyridone ring and two benzene rings were synthesized. Their single-crystal X-ray analyses exhibited three kinds of molecular aggregation: bimolecular aggregates, chiral one-dimensional structures, and achiral one-dimensional structures. In the bimolecular aggregate of (2-oxo-1, 2-dihydro-x- pyridyl) diphenylphosphines (x= 3: 2a and 6: 2c), cyclic dimers that are derived from two 2- ...
