TL;DR: In this paper, a proton in a β-position to nitrogen reacted with sodium hydride in THF to afford (N-vinylimino)phosphoranes in high yields.
Abstract: 1-[α-(Phosphoranylideneamino)alkyl]benzotriazoles, obtained by Staudin- ger phosphenimide-forming reaction of (azidoalkyl)benzotriazoles, pos- sessing 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-diphenylpyri- dines

TL;DR: Mesitylene, 2-methoxynaphthalene, 1,3,5-trimethoxybenzene, xylene and anisole were all benzotriazolylalkylated by treatment with 1-(benzenesulphonyl)benzotriaxole and an aromatic aldehyde as discussed by the authors.
Abstract: Mesitylene, 2-methoxynaphthalene, 1,3,5-trimethoxybenzene, xylene and anisole were all benzotriazolylalkylated by treatment with 1-(benzenesulphonyl)benzotriazole and an aromatic aldehyde. Upon displacement of benzotriazole, the functionalized aromatic compounds were transformed into asymmetrically trisubstituted methanes and functionalized indoles.
