Abstract

The first syntheses of 1, 3, 4-triphenylphosphole, 2-bromo-1, 3, 4-phenylphosphole and 2, 5- dibromo-1, 3, 4-triphenylphosphole are described. These phospholes, unlike most of the known derivatives, are difficult to oxidise and they and their corresponding oxides show little tendency to dimerise. The NBS mediated bromination of 1, 3, 4-triphenyl-2, 5- dihydrophosphole oxide led to the desired precursors of the corresponding phospholes ...
