An Efficient and Green Procedure for the Knoevenagel Condensation Catalyzed by Urea
TL;DR: In this paper, an efficient and green procedure for the urea catalyzed Knoevenagel condensation was developed, in which a catalytic ammount of urea, stoichiometric aldehyde and active methylene compound reacted under solvent-free conditions at 100 °C for 5-60 min to give nearly quantitative yield of product.

Microwave-assisted C–H bond activation using a commercial microwave oven for rapid deuterium exchange labeling (C–H → C–D) in carbohydrates
TL;DR: In this article, a simple commercial microwave oven and a silica-gel bath was used to obtain facile hydrogen→deuterium exchange in two model carbohydrates via stereospecific C-H bond activation.

Solvent-free N-nitrosation of secondary amines mediated by polymeric nitrosation reagent
TL;DR: A combination of cross-linked poly(4-vinylpridininium) chloride [P4-H] Cl, [II], and sodium nitrite or quaternized cross- linked poly(N-methyl-4- Vinylpyridinum) nitrite [P 4-Me] NO2, [IV], was used as effective nitrosating agents for the N-nitrosation of secondary amines under solvent-free conditions in high yields.
