Ten years of click chemistry summed up

Two recent special issues were dedicated to click chemistry and bioorthogonal chemistry.

1. Chemistry – An Asian Journal, Volume 6, Issue 10, Pages 2565–2847Special Issue: Celebrating the 10th Anniversary of Click Chemistry

October 4, 2011
Guest Editors: Qian Wang, Craig Hawker

2. Accounts of Chemical Research, Volume 44, Issue 9, Pages 651-840Special Issue: A decade of Bioorthogonal Chemistry
September 20, 2011
Guest Editor: Carolyn Bertozzi

Achievements of a decade were summed up and documented in 470-plus pages by active researchers in the field. Editors gave historical perspective as well.

Excellent resources! 

Triazole in polymer under attack by ultrasound 2

A little more work on this topic and two additions:

First, as indicated in the graph, polymer solutions are degraded by ultrasound in a controlled manner. Timothy Mason, Sonochemistry, p 18. 

Second, forward triazole formation, one of the click chemistry examples, was reported to be accelerated by ultrasound, in small molecule context. See the 2011 article and cited ones.
