Von Huisgen 1,2) wurde 1963 die 1,3-dipolare Cycloaddition 3–5) als Reaktionsprinzip zum Aufbau von Heterocyclen systematisiert. Man versteht darunter die Addition eines 1,3-Dipols 1, der aus den verschiedenen Kombinationen von Kohlenstoff-, Stickstoff- und Sauerstoffatomen bestehen kann und vier nicht dienische π-Elektronen umfast, an eine ...

Boryl Azides in 1,3-Dipolar Cycloadditions
The Journal of Organic Chemistry, 2014The 1,3-dipolar cycloaddition reaction of boron azides with alkynes has been investigated experimentally and computationally. At room temperature pinBN3 (pin = pinacolato) reacts with the strained triple bond of cyclooctyne with formation of an oligomeric boryl triazole.
