A simple method for the synthesis of 3-arylbenzophosphole
oxides
under Suzuki–Miyaura coupling conditions has been presented.
It employs benzophosphol-3-yl triflate starting materials which, prior
to our work, had not been used for the synthesis of 3-arylbenzophosphole
oxides. The reactions proceed over 24 h and provide a library of 3-arylbenzophosphole
oxides. The synthetic access to the benzophosphol-3-yl triflates has
been improved. The preliminary photophysical properties of some 3-arylbenzophosphole
oxides have been investigated by absorption and emission measurements.
The theoretical calculations were performed to establish structure–property
relationships.
