Buchwald–Hartwig Amination of Phosphinines and the Effect of Amine Substituents on Optoelectronic Properties of the Resulting Coupling Products

The Buchwald–Hartwig amination
of a phosphinine bearing
a bromophenyl moiety was carried out using a dinuclear Ni catalyst.
A variety of monoarylamines, diarylamines, and alkylamine, as well
as heterocycles, were successfully converted into novel phosphinines
bearing amine units. The photophysical properties of these novel phosphinines
were examined, including the substituent-dependent absorption/emission
features and intramolecular charge-transfer interactions.
