Staudinger ligation click chemistry
WebStaudinger Ligation. Azides react readily with triarylphosphines to form the corresponding iminophophoranes (aza-ylides) with loss of nitrogen. This transformation, originally reported by Staudinger and Meyer, 1 takes place under mild conditions and leads to excellent yields of the aza-ylide products. The initially formed iminophosphorane ... WebStaudinger ligation requires fewer harmful additives than other chemoselective ligation chemistries that have been developed for use with biological samples. Although azide-alkyne ("click") chemistry uses the same azide component s the azide-phosphine (Staudinger) chemistry, it requires special copper-containing reaction buffers that have ...
