Abstract In‐depth understanding of copolymerization kinetics and the resulting polymer microstructure is crucial for design materials with well‐defined properties. Further, insights regarding impact solvents on allows precisely tuned materials. In this regard, in situ 1 H NMR spectroscopy enables precise monitoring living anionic ring‐opening (AROP) ethylene oxide (EO) glycidyl ethers allyl eth...

An analytical method for lignins has been developed that involves derivatization followed by reductive cleavage (DFRC), depolymerization, and quantitative (31)P NMR spectroscopy. This technique detects and quantifies the various ether linkages present in softwood residual kraft lignins (RKL) and milled wood lignins (MWL). In addition, the technique supplies new quantitative information about be...

This article reviews our contribution in the field of radical synthetic chemistry, focusing on cascades relying on the use of propargylic BMDMS ethers and asymmetric synthesis using enantiopure vinylsulfoxides. THE 5-EXO-DIG CYCLIZATION OF BMDMS PROPARGYLIC ETHERS: AN EFFICIENT TRIGGER FOR RADICAL CASCADES The vinyl radical, a precious tool The vinyl radical of type 3 resulting from the highly ...

Arenediazonium o-benzenedisulfonimides have been used as efficient electrophilic partners in Cu(I) catalysed Ullmann-type coupling. The synthetic protocols are mild and easy, produced either N-alkylanilines, aryl ethers, or thioethers fairly good yields (18 positive examples, average yield 66%). o-Benzenedisulfonimide was recovered at the end of reactions reused to prepare starting salts for fu...
