1-benzotriazoles, obtained by Staudinger phosphenimide-forming reaction of (azidoalkyl)benzotriazoles, possessing a proton in a β-position to nitrogen reacted with sodium hydride in THF to afford (N-vinylimino)phosphoranes in high yields.The latter were trapped with chalcone to give the corresponding 2,4-diphenylpyridines.
