Abstract

An efficient triple-click assembly using a newly designed trivalent platform is disclosed. We achieved the selective azaylide formation of 2,3,5,6-tetrafluorophenyl azides with o-ester-substituted triarylphosphines leaving 2,6-dichlorophenyl azides untouched. Further rapid Staudinger reaction of dichlorophenyl azides and subsequent triazole formation allowed us to prepare trifunctionalized molecules in three steps.
