Cycloadditionsreaktionen am Azidliganden von Phosphan-Komplexen von Palladium(II), Platin(II) und Iridium(I).

Azides are important amine surrogates.144 The azide anion (N 3−) is an excellent nucleophile, and S N 2 displacement of primary and secondary halides (or alkyl sulfonates) with sodium azide (Section 3.2.1.1) gives the corresponding alkyl azide. The kinetics of the thermal decomposition of hexafluoroisopropylidene-p,p?-diphenyldiacyl diazide in bulk and in solution.

We speculated that the lower clickability of 1a than that of 1c is caused by stabilization of the azido group by hyper-conjugation with carbon–hydrogen bonds, which decreases the distortability of the azido group.

Customer Service. Paz Trillo, Tove Slagbrand, Fredrik Tinnis, Hans Adolfsson. 3 Although alkenyl azides generally exhibited lower clickabilities than those of alkyl azides, a sterically-hindered alkenyl azide exhibited high reactivity comparable with those of alkyl azides.

Step-Growth “Click” Coupling of Telechelic Polymers Prepared by Atom Transfer Radical Polymerization. This result and the analysis based on the frontier molecular orbitals show that the higher clickability of 1i than that of 1g is attributable to the enhanced distortability of the azido group induced by the inhibition of resonance with the additional bulky phenyl group, which surpassed the deceleration caused by the steric hindrance. Combination of photoinduced copper( Akintayo, Ziegler Thomas, C.O. Peter H. Kreutzer, Johann Ch. Unsaturation from 1d to trans-styryl azide (1e) decreased the clickability, indicating that the resonance between the azido and alkenyl groups retarded the cycloaddition (Entry 2 vs Entry 3).
