A new synthetic pathway for the preparation of benzoate-functionalized phosphanes for microwave-mediated traceless Staudinger ligations is described. Novel phosphane derivatives based on 4-substituted iodophenyl benzoates were prepared via palladium(II)-catalyzed P-C cross-coupling reaction strategy in high yields. The application of microwave conditions for the ligation reactions reduced the reaction

A 4‐fluorobenzoate‐functionalized phosphane was synthesized and reacted with different azides using the tracelessStaudingerligation as a representative sample reaction for future radiolabeling purposes with short‐lived radionuclides like fluorine‐18. For this purpose, the reaction rate was evaluated at different temperatures. The effect of starting material concentrations and the influence of the
